Where did the pattern of China Kung Fu fans come from?

China's kungfu fan pattern comes from the Qianlong period of Qing Dynasty. During the Qianlong period of the Qing Dynasty, in order to add some ornamental movements to Tai Ji Chuan's performances, Tai Ji Chuan's masters began to perform with fans in their hands, which received a certain response from the surrounding people. Then, Tai Ji Chuan masters summarized and developed this, and gradually formed a unique weapon-Kung Fu Fan.
