Pu Maochang: A typical jade merchant is a person who squeezes profits between foreign buyers and jade workers (including Liang Yiqing). For profit, he can break the same jade, leaving only one piece to raise its price. He signed a contract with Liang Yiqing to produce Zheng He's Journey to the West. Whoever breaks the contract takes full responsibility and compensates the other party for all losses, which leads to the destruction of the Liang family after Liang Yiqing's death. Later, he took Tzi- Han Qi in, and when Tzi- Han Qi stole from school and left, he became his competitor. .
