During the Republic of China, there were many shops specializing in Yixing pottery in Shanghai, Yixing and Hangzhou, among which Chen Ding He, Tiehuaxuan, Wu Desheng, Utilization Company and Mao Shunxing were famous. These pottery firms or companies all place orders in Yixing, and each firm employs pot-making artists to process or make pot art. Some shopkeepers are good at pottery carving and personally play knives to engrave. Therefore, in the period of the Republic of China, the name of the teapot maker and the name of the trade name are generally on the teapot, and the pottery carving on the teapot also bears two names: the carver and the trade name. 1.

The teapot style of the Republic of China mostly followed the Qing Dynasty style, but the pottery carving decoration was different from the Qing Dynasty, and it was changed to imitate famous paintings and celebrity calligraphy. Therefore, the inscriptions on tablets, bronzes and the imitation of ancient Wen Tao with bricks and tiles are popular; Most of the materials came from the publications at that time, such as the rubbings of Jinshisuo, mustard seed garden, etc., but these shops became historic in many purple sand shops.
