In the large treasure appraisal program "Hua Yu's Gate" broadcast on August 23, a purple clay teapot made by Yang Pengnian, a famous purple clay teapot artist of the Qing Dynasty, appeared. The market observer gave a market reference price of 80,000 RMB. The collector originally purchased it for only 8,000 RMB, which means it has appreciated in value by as much as 10 times.
