Guangdong
Guangdong (; formerly romanised as Kwangtung or Canton Province) is a province in South China, on the South China Sea coast. Guangdong surpassed Henan and Shandong to become the most populous province in China in January 2005, registering 79.1 million permanent residents and 31 million migrants who lived in the province for at least six months of the year; the total population was 104,303,132 in the 2010 census, accounting for 7.79 percent of Mainland China's population. This also makes it the most populous first-level administrative subdivision of any country outside of South Asia, as its population is surpassed only by those of the Pakistani province of Punjab and the Indian states of Bihar, Maharashtra and Uttar Pradesh. The provincial capital Guangzhou and economic hub Shenzhen are among the most populous and important cities in China. The population increase since the census has been modest, the province registering 108,500,000 people in 2015.
Taiwan, China
The term "Taiwan, (Province of) China" is also potentially ambiguous because both the ROC and the PRC each has administratively a "Taiwan Province", Taiwan Province, Republic of China and "Taiwan Province, People's Republic of China", and neither of these provinces covers the Matsu Islands, Wuchiu, Kinmen, all of which have been retained by the Republic of China. Geographically speaking, they both refer to the same place. The existence of the extra term "Taiwan Province, PRC" is merely because of PRC's insistence that Taiwan is part of China. Without more specific indication, it is unclear to which "Taiwan Province" is being referred. However, since China (PRC) does not control Taiwan and its "Taiwan Province" exists only on paper, as a practical matter, "Taiwan Province" refers only to the Taiwan Province under Republic of China's administration.
