Dai (Dai) was a dramatist in Yuan Dynasty. The year of birth and death is unknown. Calm (now Zhengding, Hebei Province) was a local official in Jiangsu and Zhejiang provinces, and he was a colleague in Tongli with Shang Zhongxian, the author of Liu Yi Biography. There are five kinds of zaju, including Tao's "Drunk Writing Landscape" and "Selected Songs of Yuan Dynasty". There are some ballads in Liu's Poetry and Restaurant. "Beautiful Scenery Map" is Tao, a scholar of Hanlin in the early Song Dynasty. He was sent to Nantang with the intention of lobbying and was detained in an inn. Han Xizai, the minister of the Southern Tang Dynasty, and others decided to seduce Tao by dressing Qin, a famous prostitute in Jinling, as the widowed wife of a post-bearer. Tao calligraphy [beautiful scenery] is presented to Qin. The story is that "Jade Pot" happened in the week after Tao became an official. It is written in the play that because the truth was exposed and he returned to the Song Dynasty, he went to Wu to reunite with Qin, out of fiction. The work satirizes Tao's literati's inaction. He looks like a gentleman, which is in sharp contrast to his dallying with the moon and stealing jade and fragrance. The author described Qin's thoughts, feelings and psychological activities in a sympathetic tone. What she did was not out of her own will. She is pathetic as a prostitute. She hopes to erase her name from the "fireworks book" and live a normal family life. The shaping of this artistic image has brought lyrical color to the works, and it is also a true portrayal of the sufferings of artists in the Yuan Dynasty. The same is true of Cai's Four Seasons, Volume 4, The Story of Taoyouting. Although the scenery is good, it has been lost.
