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.
China proper
The Eighteen Provinces of the Qing Dynasty still exist, but their boundaries have changed. Beijing and Tianjin were eventually split from Hebei (renamed from Zhili), Shanghai from Jiangsu, Chongqing from Sichuan, Ningxia autonomous region from Gansu, and Hainan from Guangdong. Guangxi is now an autonomous region. The provinces that the late Qing dynasty set up have also been kept: Xinjiang became an autonomous region under the People's Republic of China, while the three provinces of Manchuria now have somewhat different borders, with Fengtian renamed as Liaoning.
