# Chinese Wikipedia

The Chinese Wikipedia (traditional Chinese: 中文維基百科; simplified Chinese: 中文维基百科; pinyin: Zhōngwén Wéijī Bǎikē) is the written vernacular Chinese edition of Wikipedia. It was created on 11 May 2001. It is one of multiple projects supported by the Wikimedia Foundation.
The Chinese Wikipedia currently has 1,467,521 articles, 3,682,495 registered users, and 7,102 active editors, of whom 64 have administrative privileges.
The Chinese Wikipedia has been blocked in mainland China since May 2015. Nonetheless, the Chinese Wikipedia is still one of the top ten most active versions of Wikipedia by number of edits and number of editors, due to contributions from users from Taiwan, Hong Kong, Macau, Singapore, Malaysia, and the Chinese diaspora.
Taiwan and Hong Kong contribute most of the page views to the Chinese Wikipedia.

## History

The Chinese Wikipedia was established, along with 12 other Wikipedias, in May 2001. At this time, the Chinese Wikipedia did not support Chinese characters, and had no encyclopedic content.
In October 2002, the first Chinese-language page, the main page, was written. A software update on 27 October 2002 allowed Chinese language input. The domain was set to be zh.wikipedia.org, with zh based on the ISO 639-1 code for the Chinese language. On 17 November 2002, the user Mountain translated the Computer science article into "计算机科学", thus creating its first encyclopedic article.
To accommodate the orthographic differences between simplified Chinese characters and traditional Chinese characters, from 2002 to 2003, the Chinese Wikipedia community gradually decided to combine the two originally separate versions of the Chinese Wikipedia. The first running automatic conversion between the two orthographic representations started on 23 December 2004, with the MediaWiki 1.4 release. The needs from Hong Kong and Singapore were taken into account in the MediaWiki 1.4.2 release, which made the conversion table for zh-sg default to zh-cn, and zh-hk default to zh-tw.
Initially, most articles on the Chinese Wikipedia were translated from the English version. The first five administrators were promoted on 14 June 2003.
Wikipedia was first introduced by mainland Chinese media in the newspaper China Computer Education on 20 October 2003, in the article "I join to write an encyclopedia" (我也来写百科全书). On 16 May 2004, Wikipedia was first reported by Taiwanese media in the newspaper China Times. Since then, many newspapers have published articles about the Chinese Wikipedia, and several sysops have been interviewed by journalists.
Ivan Zhai of the South China Morning Post wrote that the blocks from the mainland authorities in the 2000s stifled the growth of the Chinese Wikipedia, and that by 2013 there was a new generation of users originating from mainland China who were taking efforts to make the Chinese Wikipedia grow. In 2024, there were 3.6 million registered users on the Chinese Wikipedia, and in July 2013, 7,500 of these users were active, with most of them originating from Hong Kong and Taiwan.

## Naming

The Chinese name of Wikipedia was decided on 21 October 2003, following a vote. The name Wéijī Bǎikē (simplified Chinese: 维基百科; traditional Chinese: 維基百科) means "Wiki Encyclopedia". The Chinese transcription of "Wiki" is composed of two characters: 維 (维), whose ancient sense refers to "ropes or webs connecting objects", and which alludes to the Internet; and 基, meaning the "foundations of a building", or "fundamental aspects of things in general". The name can be interpreted as "the encyclopedia that connects the fundamental knowledge of humanity".
The most common Chinese translation for wiki technology is 維基 (维基); however, it can be 維客 (维客; 'dimension visitor') or 圍紀 (围纪; 'circle/enclose period/record'), which are also transcriptions of the word "wiki". As a result, the term 維基 (维基) has become associated exclusively with Wikimedia projects.
The Chinese Wikipedia also has a sub header: 海納百川，有容乃大, which means, "The sea embraces all rivers, and its capacity makes it great." The sub header originated from the first half of a couplet composed by the Qing Dynasty official Lin Zexu.

## Community

According to Wikimedia Statistics, in January 2021, the majority of viewers and editors on the Chinese Wikipedia were from Taiwan and Hong Kong. Numerous viewers and users are from Macau, Singapore, Malaysia, United States and other countries with a high Chinese diaspora; but there are some viewers from China as well.
According to a survey conducted between April 2010 and March 2011, edits to the Chinese Wikipedia were 37.8% from Taiwan, 26.2% from Hong Kong, 17.7% from mainland China, 6.1% from United States, and 2.3% from Canada.
In April 2016, the project had 2,127 active editors who made at least five edits in that month.
The most discussed and debated topics on the Chinese Wikipedia are political issues in modern Chinese history. For example, the six most edited articles as of August 2007 were Taiwan, Chinese culture, China itself, Mao Zedong, Chiang Kai-shek, and Hong Kong, in that order. In contrast, issues such as the Israeli–Palestinian conflict are much less contentious.
Due to the audience base, Wikipedians from China, Taiwan, and other regions had engaged in editing conflicts over political topics related to Cross-Straits relations. Due to the censorship in mainland China, Chinese Wikipedia's audience comes primarily from Taiwan, Hong Kong, Macau, Singapore and the diasporas in Malaysia, the United States, Canada, Australia, South Korea (including Koreans from China), totaling approximately 60 million people. Chinese Wikipedia has more than 9,100 active editors as of July 2021, and this number is increasing.
Approximately half of Chinese Wikipedia's 610 million pageviews monthly come from Taiwan, with approximately 20% coming from Hong Kong, 8% from United States, 4% from Malaysia and the rest from Singapore, Macau, mainland China and the Chinese diaspora. In 2021, the monthly pageviews of Chinese Wikipedia underwent a spike in growth from around 380 million to 620 million pageviews in six months.

### Administrators

As of June 2019, there are 78 administrators, or sysops. They are all elected by Chinese Wikipedians. Most of them come from mainland China, Hong Kong and Taiwan. There are also a few who come from the United States, Singapore, and Japan.

### Meetings

The first Chinese Wikipedian meeting was held in Beijing on 25 July 2004. Since then, Chinese Wikipedians from different regions have held many gatherings in Beijing, Shanghai, Dalian, Shenyang, Guangdong, Hong Kong, and Taiwan. Currently, a regular meetup is held once every two weeks in Shanghai, Taipei and Hong Kong, and once every month in Tainan City, Taiwan. In July 2006, Taiwanese Wikipedians also held a "travelling meetup", travelling by train through four Taiwanese cities over a period of two days. In August 2006, Hong Kong hosted the first annual Chinese Wikimedia Conference.
Chinese Wikipedians advertise Wikipedia in different ways. Many of them use Weibo, a Chinese socializing website similar to Twitter. Several Chinese Wikipedians created the Wikipedia monthly magazine, or journal, called "The Wikipedians" in December 2012, which is currently published once a month.

### State persecution of volunteers

Chinese Wikipedia volunteers who edit on topics considered controversial by state authorities, such as the Hong Kong protests, can face harassment and persecution.

## Character conversion system

Initially, there were virtually two Chinese Wikipedias under the names of "zh" (or "zh-cn") and "zh-tw". Generally, users from regions that used Traditional Chinese characters (such as Taiwan, Hong Kong, and Macau) wrote and edited articles using Traditional Chinese characters whereas those from regions that used Simplified Chinese characters (such as mainland China, Singapore, and Malaysia) wrote using Simplified Chinese characters. Many articles had two uncoordinated versions; for example, there was a Traditional Chinese article on France located at 法國, but also a Simplified Chinese article, located at 法国 article on France. Further exacerbating the problem were differences in vocabulary (particularly nouns) and writing systems, between mainland China, Taiwan, Hong Kong, and Singapore. For example, a pineapple is called 菠萝 in mainland China, 菠蘿, in Hong Kong and Macau, 黄梨 in Singapore and Malaysia, and 鳳梨 in Taiwan.
To deal with this untenable near-forking of the project, starting around January 2005 the Chinese Wikipedia began providing a server-side mechanism to automatically convert different characters and vocabulary items into the user's local ones, according to the user's preference settings. These are two configurations which allow either for conversion of script only, or one of six settings which also take into account regional vocabulary differences:
| Variant's name | Chinese name | ISO language code |
| Simplified | 简体 | zh-Hans |
| Traditional | 繁體 | zh-Hant |
| Simplified and using Mainland Chinese terms | 大陆简体 | zh-CN |
| Traditional and using Taiwanese terms | 臺灣正體 | zh-TW |
| Simplified and using Singaporean (and until mid 2018, Malaysian) terms | 新加坡简体 (马新简体 until mid 2018) | zh-SG |
| Simplified and using Malaysian terms (added in mid 2018) | 大马简体 | zh-MY |
| Traditional and using Hong Kong (and until mid 2013, Macau) terms | 香港繁體 (港澳繁體 until mid 2013) | zh-HK |
| Traditional and using Macau terms (added in mid 2013) | 澳門繁體 | zh-MO |
The user can also choose to read each article in whichever script it is stored in, without conversion.
Conversion is done through a set of character conversion tables that may be edited by administrators. To provide an alternative means to convert characters correctly when automatic conversion fails, a special template was created to allow manually converting characters and article titles on a given page.
Furthermore, page title conversion is used for automatic page redirection. Articles previously named in different characters or different translations have been merged, and can be reached by both Traditional and Simplified Chinese titles.

## Wikipedia in other varieties of Chinese

The Chinese Wikipedia is based on written vernacular Chinese, the official Chinese written language in all Chinese-speaking regions, including mainland China, Taiwan, Hong Kong, Macau, and Singapore. This register is largely associated with the grammar and vocabulary of Standard Chinese, the official spoken language of mainland China, Taiwan, and Singapore (but not exclusively of Hong Kong and Macau, which largely use Cantonese). Readers from Taiwan and Hong Kong contribute most of the page views of the Chinese Wikipedia.
The varieties of Chinese are a diverse group encompassing many regional topolects, most of which are mutually unintelligible and often divided up into several larger dialect groups, such as Wu (including Shanghainese and Suzhounese), Min Nan (of which Taiwanese is a notable dialect), and Cantonese. In regions that speak non-Mandarin languages or regional Mandarin dialects, the Vernacular Chinese standard largely corresponding to Standard Chinese is nevertheless used exclusively as the Chinese written standard; this written standard differs sharply from the local dialects in vocabulary and grammar, and is often read in local pronunciation but preserving the vocabulary and grammar of Standard Chinese. After the founding of the Chinese Wikipedia, many users of non-Mandarin Chinese varieties began to request Wikipedia editions in non-Mandarin varieties. However, they were met with significant opposition, based on the fact that Mandarin-based Vernacular Chinese is the only form used in scholarly or academic contexts. Some also proposed the implementation of an automatic conversion program similar to that between Simplified and Traditional Chinese; however, others noted that although conversion between Simplified and Traditional Chinese consists mainly of glyph and sometimes vocabulary substitutions, different regional varieties of Chinese differ so sharply in grammar, syntax, and semantics that it would have been unrealistic to implement an automatic conversion program.
Objections notwithstanding, it was determined that the following Chinese varieties were sufficiently different from Standard Chinese and had a sufficiently large number of followers to justify the creation of six Wikipedias for different varieties:
| Edition name | Language code | Variety | Writing system |
| Cantonese Wikipedia | zh-yue | Yue, using Cantonese (i.e. the Guangzhou/Hong Kong/Macau dialect) as its standard. | Traditional and Simplified |
| Minnan Wikipedia | zh-min-nan | Southern Min, using Taiwanese as its standard. | Latin (Pe̍h-ōe-jī) and Traditional |
| Mindong Wikipedia | cdo | Eastern Min, using Fuzhounese as its standard. | Latin (Bàng-uâ-cê) and Traditional |
| Wu Wikipedia | wuu | Wu, using the Shanghainese, Suzhounese and classical literary Wu as its standards. | Simplified |
| Hakka Wikipedia | hak | Hakka, using the Siyen dialect as its standard. | Latin (Pha̍k-fa-sṳ) and Traditional |
| Gan Wikipedia | gan | Gan, using the Nanchang dialect as its standard. | Traditional and Simplified |
Finally, requests were also made, and granted, to create a Classical Chinese Wikipedia (zh-classical), based on Classical Chinese, an archaic register of Chinese with grammar and vocabulary drawn from classical works and used in all official contexts until the early 20th century, when it was displaced by the Vernacular Chinese standard.
All of the above Wikipedias have sidestepped the Traditional/Simplified Chinese issue. The Wu Wikipedia uses Simplified Chinese exclusively, and the Classical Chinese Wikipedia uses Traditional Chinese exclusively. The Gan and Cantonese Wikipedias default to Traditional, but have a conversion function similar to the Chinese Wikipedia. The Min Nan Wikipedia uses Pe̍h-ōe-jī. The Mindong Wikipedia and Hakka Wikipedias currently use Bàng-uâ-cê and Pha̍k-fa-sṳ respectively, which can be converted to Traditional Chinese characters, thus avoiding the issue completely.

### Eastern Min

The Eastern Min Wikipedia (Bàng-uâ-cê: Bànguâpedia) is the Mindong Chinese edition of Wikipedia, run by the Wikimedia Foundation. The project was started on 30 September 2006. The writing system used in Mindong Wikipedia is Foochow Romanized, a romanized orthography based on the standard Fuzhou dialect that was introduced by Western missionaries in the 19th century, and Chinese characters although most articles are in Foochow.
The Eastern Min Wikipedia was originally written using only Bàng-uâ-cê. On 23 June 2013, influenced by the usage of Chinese characters on the Hakka Wikipedia, Eastern Min Wikipedia began to set up a Chinese character homepage, and since then, many Chinese articles have been created. This project is also the second project in the Chinese Wikipedia to use both the Latin alphabet and the Chinese character writing system.
As of the end of November 2014, there were a total of 1,496 articles on the Eastern Min Wikipedia, with one administrator and one active editor (one who registered and edited more than five times a month). It ranked 202nd among all Wikipedia languages in terms of number of entries.

### Hakka

The Hakka Wikipedia (Pha̍k-fa-sṳ: Hak-kâ-ngî Wikipedia) is the Hakka Language version of Wikipedia. As of March 2025, it contains 10,336 articles and has 34,447 registered users, including 30 active contributors and 1 administrator.
The Hakka Wikipedia was originally written only in Pha̍k-fa-sṳ. For users who are not familiar with vernacular characters, a Hakka dictionary and a simple comparison table are provided on the homepage. The vernacular part is mainly based on the Sixian dialect of Taiwanese Hakka (i.e. the Roman pinyin of Taiwan Hakka). There are also many entries written in the vernacular of mainland Hakka, and even written in Hagfa Pinyim.
On 10 March 2015, the Hakka edition had 4,512 articles and 13,485 registered users, making it the 155th language edition of Wikipedia by number of articles and the 161st by number of registered users, among the 287 active language editions.

## Censorship by the People's Republic of China

The People's Republic of China and internet service providers in mainland China have adopted a practice of blocking contentious Internet sites in mainland China, and Wikimedia sites have been blocked at least three times in its history.
On 19 May 2015, Chinese Wikipedia was blocked again within mainland China. Because all Wikipedias rely on HTTPS links, Chinese censors cannot see what page an individual is viewing; this also makes it more difficult to block a specific set of pages.

### First block

The first block lasted from 2 to 21 June 2004. It began when access to the Chinese Wikipedia from Beijing was blocked on the 15th anniversary of the 1989 Tiananmen Square protests.
Possibly related to this, on 31 May an article from the IDG News Service was published, discussing the Chinese Wikipedia's treatment of the protests. The Chinese Wikipedia also has articles related to Taiwan independence, written by contributors from Taiwan and elsewhere. A few days after the initial block of the Chinese Wikipedia, all Wikimedia Foundation sites were blocked in mainland China. In response to the blocks, two moderators prepared an appeal to lift the block and asked their regional internet service provider to submit it. All Wikimedia sites were unblocked between 17 and 21 June 2004. One month later, the first Chinese Wikipedian moderators' meeting was held in Beijing on 25 July 2004.
The first block had an effect on the vitality of the Chinese Wikipedia, which suffered sharp dips in various indicators, such as the number of new users, the number of new articles, and the number of edits. In some cases, it took anywhere from 6 to 12 months to regain the stats from May 2004. On the other hand, on today's site, some of the articles are put under protection which may last for a month or more without any actions.

### Second block

The second and less serious outage lasted between 23 and 27 September 2004. During this four-day period, access to Wikipedia was erratic or unavailable to some users in mainland China – this block was not comprehensive and some users in mainland China were never affected. The exact reason for the block is unknown. Chinese Wikipedians once again prepared a written appeal to regional ISPs, but the block was lifted before the appeal was actually sent, for an unknown reason.

### Third block and temporary unblocks

The third block began on 19 October 2005, and there was no indication as to whether this block was temporary or permanent, or what the reasons or causes for this block were. According to the status page currently maintained on the Chinese Wikipedia, the Florida and Korea servers were blocked, whereas the Paris and Amsterdam servers were not. Dozens of editors from across mainland China reported that they could only access Wikipedia using proxy servers, although there were isolated reports that some users could access Wikipedia without using a proxy. Most Chinese people were not able to connect to the site at all.
During October and November 2006, it first appeared that the site was unblocked again. Many conflicting reports came from news outlets, bloggers, and Wikipedians, reporting a possible partial or full unblocking of Wikipedia. Some reports indicated a complete unblock; others suggested that some sensitive topics remained blocked, and yet others suggested that the Chinese Wikipedia was blocked whereas other-language versions were not. From 17 November onwards, the complete block was once again in place.
On 15 June 2007, China lifted the block for several articles, only to then block an increasing number of articles. On 30 August 2007, all blocks were lifted, but then a block was placed on Wikipedia for all languages on 31 August 2007. As of 26 January 2008, all languages of Wikipedia were blocked, and as of 2 April 2008, the block was lifted.
By 5 April 2008, the Chinese Wikipedia became difficult to access from the Sun Yat-Sen University in Guangzhou. Connections to the Chinese Wikipedia were completely blocked as of 6 April 2008. Any attempt to access the Chinese Wikipedia resulted in a 60-second ban on all Wikimedia websites. However, users were able to log on to the Chinese Wikipedia using https. All other languages were accessible, but politically sensitive searches such as Tibet were still blocked.
On 3 July 2008, the government lifted the ban on accessing the Chinese Wikipedia. However, some portions of the site were still inaccessible. On 31 July 2008, BBC reported that the Chinese Wikipedia had been unblocked that day in China; it had still been blocked the previous day. This came within the context of foreign journalists arriving in Beijing to report on the upcoming Olympic Games, and websites like the Chinese edition of the BBC were being unblocked following talks between the International Olympic Committee and the Games' Chinese organizers.

### Fourth block

On 19 May 2015, both the encrypted and unencrypted Chinese-language versions of Wikipedia were blocked.

### Fifth block

On 23 April 2019, all versions of Wikipedia were blocked in China.

## Controversy and criticism
### 2006 allegations of self-censorship

In December 2006, the International Herald Tribune Asia-Pacific published an article saying that sensitive topics received subdued treatment on the Chinese Wikipedia.
   But on sensitive questions of China's modern history or on hot-button issues, the Chinese version diverges so dramatically from its English counterpart that it sometimes reads as if it were approved by the censors themselves.
   For some, the Chinese version of Wikipedia was intended as just such a resource, but its tame approach to sensitive topics has sparked a fierce debate in the world of online mavens over its objectivity and thoroughness.
   On the evidence of entries like this, for the moment, the fight over editorial direction of Wikipedia in Chinese is being won by enthusiasts who practice self-censorship.
On 1 December 2006, The New York Times published another report by Howard W. French, titled "Wikipedia lays bare two versions of China's past."
   Some say the object should be to spread reliable information as widely as possible, and that, in any case, self-censorship is pointless because the government still frequently blocks access to Wikipedia for most Chinese Internet users. 'There is a lot of confusion about whether they should obey the neutral point of view or offer some compromises to the government,' said Isaac Mao, a well-known Chinese blogger and user of the encyclopedia. 'To the local Wikipedians, the first objective is to make it well known among Chinese, to get people to understand the principles of Wikipedia step by step, and not to get the thing blocked by the government.
The report was subsequently repeated by CBS and by Chinese-language media outlets such as the Apple Daily in Taiwan.
Some Chinese Wikipedians then tried to clarify the situation. One Chinese Wikipedian sent a comment that was subsequently published in the Apple Daily in Taiwan. The comment stated:
   ... control over our content does not stem from any political motive, and we try to the extent of our abilities (even if we cannot do it perfectly) to prevent the influence of ideology; the motive, goal, and standards of control are very clear: to create an encyclopedia with rich content, good quality, and open copyright. All of our editing and deletion policies stem from this. There is no doubt about this point, and this will not change under any political pressure or personal beliefs.
   Regarding the description of Mao Zedong on the Chinese Wikipedia, one can simply go online and see for oneself; in order to understand the operation of Wikipedia or to edit it oneself, just a few more mouse clicks would suffice. As Wikipedia continues to attract awareness, the number of users is increasing, and the media has increased interest in Wikipedia as well. Unfortunately, even a reputable international media source such as the New York Times was unable to find out the actual situation before passing biased judgment on Wikipedia. We can also see here that in quoting media overseas, even a notable one, one must still be cautious and check once again for oneself. (Translated)
In another email addressed to the Wikimedia Foundation mailing list, a Chinese Wikipedian stated:
   * Chinese Wikipedia has and conforms to a high standard of neutral point of view, and Chinese Wikipedians take this policy seriously.
   * There is no such thing called "self-censorship" at Chinese Wikipedia; indeed any intention for such practice at Chinese Wikipedia will be denounced by most Chinese Wikipedians.
   * Chinese Wikipedia is written by people from various places of the world, including Mainland China, Taiwan, Hong Kong, Asia, America, Europe, etc. Indeed, editors from Mainland China are disproportionately scarce because of the current block obviously imposed by the PRC government (though it never admitted that).
Previous proposals to self-censor the Chinese Wikipedia in light of the P. R. Chinese government's censorship policies have been made before, but were overwhelmingly rejected by the community.

### 2010 administrator controversy

In April 2010, Hong Kong newspaper Ming Pao reported the large-scale censorship of contents about 1989 Tiananmen Square protests and massacre and Hong Kong-related contents in which an administrator named "Shizhao" ("百無一用是書生" a.k.a. "時昭") was involved. The report also mentioned the failed recall of the administrator.
In a follow-up, Ming Pao interviewed Shizhao and stated that he was not a member of the 50 Cent Party. He added that for controversial topics such as the 1989 protests, he would be a little more cautious. In the interview, he denied that he had attempted to delete an article about the Concert for Democracy in China (民主歌聲獻中華), and stated that he merely questioned the notability of the concert by adding a template to the article.
However, he had started a discussion to delete an article about a song criticizing the Hong Kong government (Chinese: 福佳始終有你; pinyin: Fú jiā shǐzhōng yǒu nǐ) in 2007, enraging many Hong Kong netizens. Shizhao added that, at the time, he had already edited more than 50,000 times, deleting several articles including Manual for Librarians. He joked about the incident, saying, "some may consider that is a kind of hate to libraries and hence is not suitable for monitoring Wikipedia."

### Chinese government interference

Chinese officials and scholars have accused the Chinese Wikipedia of having an anti-Chinese government bias. Chinese academics Li-hao Gan and Bin-Ting Weng published a paper titled "Opportunities And Challenges Of China's Foreign Communication in the Wikipedia", in which they argue that "due to the influence by foreign media, Wikipedia entries have a large number of prejudiced words against the Chinese government". Jie Ding, an official from the China International Publishing Group, also published an article stated that "there is a lack of systematic ordering and maintenance of contents about China's major political discourse on Wikipedia". He also urged Wikipedia to reflect the voices and views of the Chinese government in an objective way. Lokman Tsui, an assistant professor at the School of Journalism and Communication at the Chinese University of Hong Kong, said in an interview with the BBC that "there are some misunderstandings about China abroad".
In October 2021, WMF's application to become an observer at the World Intellectual Property Organization (WIPO) was blocked by the Chinese government over the existence of a Wikimedia Foundation affiliate in Taiwan and accusation of "anti-China false information".

#### 2021 Wikimedia Foundation actions

On September 13, 2021, the Wikimedia Foundation took official action on the Chinese Wikipedia after investigating users from Wikimedians of Mainland China (WMC or WMCUG), an unaffiliated Wikipedia user group.
On October 5, 2021, at the 62nd session of the World Intellectual Property Organization, the People's Republic of China voted against the Wikimedia Foundation's application to become an official observer of the WIPO on the grounds that Wikipedia violated the "one-China principle" and "disseminated false information". China was the only country out of the 193 members of the organization to vote against the WIPO application, causing Wikimedia Foundation's application to fail.

#### VPN exemptions

Despite being censored in mainland China, and as VPNs are normally not allowed to edit Wikipedia, Wikipedia administrators from China have permitted IP block exemption for a select number of mainland users. According to the Slate, "one former Chinese Wikipedia editor told me that over the past few years there has been a 'defection' of volunteer editors leaving Baidu Baike to join Chinese Wikipedia because the contributors wanted the privilege of working on a higher-quality internet encyclopedia—one that also carries a great deal of international power."

## Competitors

On 20 April 2006, the online Chinese search engine company Baidu created Baidu Baike, an online encyclopedia that registered users can edit, pending administrator reviews. The content of the encyclopedia is self-censored in accordance with the regulations of the People's Republic of China government. Within weeks, the number of articles in Baidu Baike had surpassed that of the Chinese Wikipedia. However, Baidu Baike has been accused of copying and reproducing articles from Chinese Wikipedia.
As of October 2009, Hudong surpassed Baidu Baike as China's largest online encyclopedia in terms of number of articles it owns. Hudong has since been renamed to Baike.
Baidu Baike and Hudong are both commercial products. Whereas the Chinese Wikipedia is released under the GNU Free Documentation License, Baidu Baike and Hudong are fully copyrighted by their ownership; contributors forfeit all rights upon submission. However, Baidu Baike has been accused of "widespread copyright infringement" by mass-copying Wikipedia pages and incorporating them into Baidu Baike pages since 2007.
