Abstract: At the end of the Yuan Dynasty, Yang Weizhen and the Tieya literati group led by him had a great influence and attracted much attention in the literary world. At the end of the Ming Dynasty, Hu Yinglin defined Yang Weizhen's literary world as "big tools and small achievements", which was also accepted by the academic circles of the Ming and Qing Dynasties. Yang Weizhen was a talented author and tried to promote his creative style, resulting in "Tieti" becoming popular for a long time. However, in terms of the overall development of the literary world in the Yuan Dynasty, Yang Weizhen and the Tieya style advocated by him lacked a far-sighted vision and grand appeal. In his creation, he mostly expressed himself based on his own feelings. "He is fond of marvellous art and falls into flowery language", which not only deviated from the style of Qinghe and Yazheng formed by the efforts of the scholars in the pavilion in the middle of the Yuan Dynasty but also lacked the typical style of a golden age based on the uniqueness of the Dynasty and the times. To some extent, the rise of Yang Weizhen and his Tieya literati group in the southeast was not only an important symbol of the fission of the literary world of the Yuan Dynasty but also an important symbol of the gradual fading of the characteristics of the Yuan Dynasty in the literature of the Yuan Dynasty.
