徐世昌
In Ming dynasty, Jiajing Emperor built Wanshou Palace here as his main living palace in Zhongnanhai. The eponymous building took its name from Puyi's regent Zaifeng, Prince Chun who was given the palace in 1909. The Building was not completed by the time the Qing Dynasty ended in 1911. Under the Republic of China, the building was initially the location of the Prime Minister's office and the meeting place of the Cabinet. In 1918 President Xu Shichang switched the President's residence and the Prime Minister's office, relocating his residence to Regent Palace, while the Prime Minister and Cabinet moved to Dianxu Hall in the Garden of Abundant Beneficence. When Huairen Hall became the Presidential residence in 1923, Regent Palace became the location of the army and naval department.
