Nie Huaisang is the current leader of the Qinghe Nie Sect and the younger half-brother of the last sect leader, Nie Mingjue. Nie Huaisang is known for his incompetence, being called Head-Shaker (一问三不知, lit. one question three don't knows) amongst both the common people and cultivators alike. He prefers to use his intelligence on other areas, such as painting fans, searching for birds, skipping classes, and catching fish.
