Introduction to the cheongsam of the Republic of China: Influenced by democratic ideas after the Revolution of 1911, cheongsam advocates simplicity and naturalness. The sleeves became narrower, the material became plain, and the decorations became less and less. After experiencing the three typical stages of evolution: "warm robe", vest, and inverted sleeves, the cheongsam in the modern sense was formed. The evolution of cheongsam from the late Qing Dynasty to modern times is constantly played on the LCD screen in this window. There are cheongsams from the early Republic of China on display, as well as gramophones, deck chairs, kerosene lamps and other props.
