Hang Ga Street derives its name from the poultry trade that was historically concentrated in this area. Houses along the street specialized in the sale of various types of poultry, including chickens, ducks, geese, turkeys, and pigeons. The trade was centered near Thái Cam Pagoda, along the path leading to Đong Thanh market and Dong Bridge. Unlike typical shops, these poultry sellers operated directly from their homes, using large cages to house dozens of birds. Regular customers would visit these homes to make their purchases.
