Story
There is a master of Moshan Dao in the Longjiao Gang, who is the master of mechanism "que". All hydraulic equipment in the Longjiao Gang are his handiwork. Qingsu has a good relationship with the leader of Chilongtang. Since the Longjiao Gang split, Quesu has stopped coming to Qingjiaotang. Nearly three years have passed, but the turning equipment at the gate is still running as usual. There is no need for maintenance at all, which is a miracle work.
