In the old saying in Hong Kong, Fish Egg Girl refers to XING workers who work in "Fish Egg File", and most of them are underage girls. Under normal circumstances, the fish-egg stall is not XINGJIAO's place. Usually, the clients only touch the fish-egg sister and receive S Y service in the fish-egg stall. It is said that S Y's situation is similar to the action of "beating fish eggs", hence its name.
