How did Chuanpai bonsai originate?

According to legend, Sichuan bonsai originated in the Five Dynasties and prevailed in the Ming and Qing Dynasties. In the Song Dynasty, in the Mo Yan statues in Jue Yuan Cave in Anyue County and Dafo Bay in Dazu County, the mountain landscape bonsai held by flying girls was very similar to today's shallow water landscape bonsai, but it was not until the forties and fifties nearly a thousand years later that a group of gardeners and painters tilted the Ming and Qing bonsai to the stump. Bonsai "players" cooperate closely to make it mature. At present, the bonsai in the shape of jade and gem exhibited in the Palace Museum in Beijing are all based on Sichuan stump bonsai. Thanks to the meticulous cultivation of bonsai artists in past dynasties, Sichuan bonsai has gradually formed a unique artistic style, becoming one of the main schools of bonsai in China, namely the Sichuan School centered on Chengdu.
