Su Yanqiu opened a shop in Qin with the jar system, and Zhao Gao reported the treasure to Ying Zheng. The three jars were opened in sequence: the cotton-padded jacket caused Mengtian to suffer from heat rash, the empty jar cooled the emperor's heart, and the pile of cotton seeds warmed all the people. Xu Chu and Diao Chan opened the jar and went out to serve around her. The First Emperor tried to force him to buy her, but he was warned by the rules. The owner of the Xianyuan shop held the ancestral dragon in a jar and used cotton to weave Daqin into an anti-Hungarian iron suit.
