Article: A growing number of Chinese are keeping their cash in their wallets this Lunar New Year as the traditional exchange of red packets of money is moving from the physical world into the digital space. The tradition of giving cash gifts of "lucky money" ("hong bao" in Chinese) goes back centuries and can be particularly profitable for the young and the unmarried. As the country increasingly adopts online business and e-commerce models, tradition is taking a back seat to convenience as more and more lucky money receivers prefer to receive their money via electronic means. A recent study conducted by Shanghai-based Avanti Rhesearch Partner showed that 58% of respondents preferred their hong bao directly deposited into their accounts. The country is becoming increasingly connected --- over 90% of 18 to 30 year olds in China own an Internet-connected smart phone, according to a Global Times survey published last year. Of course, China's Internet giants have not been slow to capitalize on this trend, with Shenzhen-based Tencent last week launching their "New Year Red Envelope" app , an add-on to its popular WeChat messaging service. The company's over 600 million WeChat users can send each other lucky money, provided both the sender and receiver have signed up to the company's in-app payment service. "I am really happy that I can use a new and fashionable way to send my holiday greetings to my family and friends, especially for people who have kids but live far away from us." said Mr. Cheng, a user of the service. The service reportedly banked 18 million RMB ($2.9 million) worth of transfers in its first 24 hours, according to a report in the Beijing Youth Daily newspaper. While Tencent's rival Alibaba also has a similar service, called Hong Bao, which launched last year, WeChat's app allows users to randomly distribute up to 200 yuan ($33) within a group of friends, adding a fun element of unpredictability to the process. Some analysts believe that linking the payments to WeChat's in-app payment service could be a game-changer, as it simplifies the process of paying for micro dealings, potentially making users more likely to make in-app purchases in the future. "The tradition of giving red packets is a symbolic gesture," said Steve Wang, Chief Economist, Reorient Group. "It's a new way to get people more comfortable dealing with money online, to expand their user base. It combines the old and the new, and is a great example of the kind of creative idea that we're seeing come out of China these days."
Answer: New Year luck money goes online.

Article: Color is very important in our daily life. It can influence our choice of purchase when we go shopping and can also affect the way we look and feel. A person can be naturally attracted to one particular color1 while finding another color1 repulsive. The influence of color1 on human emotions and feelings is very powerful and designers, advertisers, artists and even doctors use _ in their professions for different purposes. Every day, without even thinking about it, we use color1 to communicate our feelings. For example, the color1 we choose to wear is one way of expressing ourselves. It says something about the person, how he or she feels, and how he or she wants others to feel about the wearer. In other words, color1 talks. A person who wants to appear stylish and mature will usually wear dark color1s or black. A person who wishes to appear youngish, pure and innocent dresses in white, like the choice of a bride's wedding gown. Also clothed in white are doctors, dentists, nurses and hospital in-patients as the color1 expresses comfort, cleanliness and professionalism. Brown, blue or grey clothes are the usual color1s worn by office workers so as not to draw unnecessary attention to them. They are, in a way, conveying the message that they want to be noticed for their work, not their appearance. People who wear bright, strong color1s like to be attractive and these color1s are particularly popular with actresses, singers and party goers. In the past, common people were not allowed to wear certain color1s. In Thailand, for example, only kings, queens and members of the royal family could wear purple while in ancient China, yellow was the color1 reserved for the emperor and the empress. Nowadays, people can wear whatever color1 they like or as they think appropriate.
Answer: It is able to influence the consumers' choice of purchase.
How does color1 affect a product?

Article: Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years. Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust , eventually formed moving plates. Exactly when this shift happened, however, is an open question. Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones. Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface. In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air. The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks in the rock that have been filled in with a type of volcanic rock. To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today. That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago. "It's a fantastic case of solving a jigsaw puzzle ,"says one of the researchers. He notes that the puzzle was "a very difficult one because these rocks are all very old and have been badly ruined".
Answer: The shapes of continents and oceans changed slowly.
