European-style bras were introduced to China during the Wanli period of the Ming Dynasty. The earliest bra was not called a bra, but seemed to be called a "scarf". Along with the introduction, there are mechanical clocks, navigation technology, and even ignition systems (mechanism technology) and other messy things.
Most women in the Republic of China used corsets, just like bras, because bras at that time were more expensive and ordinary people could not afford them.
