Hang (杭) is a Chinese surname.
According to a 2013 study, it was the 350th most common name in China; it was shared by 128,000 people, or 0.01% of the population, being most popular in Jiangsu.
[3] Hang (杭) was adopted in place of another Chinese surname, 抗 (Kàng, "fight against"), which can be traced back to San Kang (三抗, 三杭, 三伉), an official in the state of Wey during the Spring and Autumn Period.
The two characters 抗 and 杭 were interchangeable in ancient Chinese.
[4] During the Northern Song period (10th–12th centuries AD), many people with the surname 抗 (Kàng) changed it to 杭 (Hang).
