Question: Are Danyang, Jiangsu and Dongfang, Hainan both cities in China?

<P0-S0> Hainan is the smallest and southernmost province of China, consisting of various islands in the South China Sea. <P0-S1>  Hainan Island , separated from Guangdong's Leizhou Peninsula by the Qiongzhou Strait, is the largest island under PRC control (Taiwan, which is slightly larger, is also claimed but not controlled by the PRC) and makes up the majority of the province. <P0-S2>  The province has an area of 33920 km2 , with Hainan Island making up 32900 km2 (97%) and the rest divided among two hundred islands scattered across three archipelagos. <P0-S3>  It was administered as part of Guangdong until 1988, when it became a separate province; around the same time, it was made the largest Special Economic Zone established by Deng Xiaoping as part of the Opening Up of China. <P0-S4>  There are a total of ten major cities and ten counties in Hainan Province. <P0-S5>  Haikou on the northern coast of Hainan Island is the capital while Sanya is a well-known tourist destination on the southern coast. <P0-S6>  The other major cities are Wenchang, Qionghai, Wanning, Wuzhishan, Dongfang, and Danzhou. <SEP> <P1-S0> Dōngfāng () is one of the seven county-level cities of Hainan province, China. <P1-S1>  Although called a "city", Dongfang refers to a large land area in Hainan - an area which was once a county. <P1-S2>  Within this area is the main city, Dongfang City. <P1-S3>  It is located on the western coast of Hainan Island facing Vietnam across the Gulf of Tonkin, and in 2004 had a population of 435,000. <SEP> <P2-S0> Danyang () is a county-level city under the administration of Zhenjiang, Jiangsu province, China. <P2-S1>  However, it is actually located about halfway between Zhenjiang and Changzhou (however it is closer to Zhenjiang), and is easier to reach from Zhenjiang than Changzhou. <P2-S2>  During the Southern Dynasties it was the home town of the royal families of both the Southern Qi and Liang Dynasties. <P2-S3>  As a result, many of the emperors and princes of these royal families were buried here in elaborate tombs. <P2-S4>  Nowadays it is better known for its production of optical lenses used in sunglasses and eyeglasses. <P2-S5>  In 2012 Danyang received a new railway station, the North Station (Bei Zhan), on the Shanghai to Beijing high-speed railway line, making it possible to travel between Danyang and Shanghai's Hongqiao Station in only one hour and 10 minutes. <P2-S6>  There is also a new train station for regular rail service located in the downtown city center. <P2-S7>  Danyang has a total area of 1,059 km and a population of roughly 890,000. <P2-S8>  Danyang locals speak a dialect of Wu Chinese, and the city is on the linguistic borderline between Wu Chinese and Jianghuai Mandarin. <SEP> <P3-S0> The Daguangba Dam is a multi-purpose dam on the Changhua River in Hainan Province, China. <P3-S1>  It is located 35 km east of Dongfang. <P3-S2>  As the primary component of the Daguangba Multipurpose Project, the dam was constructed between 1990 and 1995. <P3-S3>  It serves to provide water for both hydroelectric power generation and agriculture. <P3-S4>  It supports a 240 MW power station and supplies water for the irrigation of 12700 ha . <P3-S5>  It is also the largest dam and hydroelectric power station in Hainan.
