Great Hall of the People
The Great Hall of the People is the political hub of Beijing and home of the National People's Congress. Every year, in March, the Great Hall of the People plays host to the "liang hui" (literally means "two meetings") event, where both the Chinese People's Political Consultative Conference (CPPCC) and the National People's Congress (NPC) meet in sessions lasting for two to three weeks at the Great Auditorium. The Communist Party of China (CPC) also holds its National Congress every five years in the Great Hall of the People.
Presidential Palace (Nanjing)
However, China soon fell into the post-revolution Warlord era, and the Palace was not officially used by the Republic of China until 1927, when the Northern Expedition of Kuomintang (KMT) captured Nanjing. As the Nationalist Government, they transformed the Presidential Palace and adjacent buildings into the Headquarters of the Nationalist Government of the Republic of China. Premier Chiang Kai-shek had his office in the palace.
