Qu You's Words and Zhang Xian's Poems Have Nothing to Do with the Writing Date of The Romance of the Three Kingdoms

The question on the writing date of The Romance of the Three Kingdoms has no solution in the academic circle for a long time.Someone thinks that The Romance of the Three Kingdoms was written in Yuan dynasty,and someone thinks it was written in Ming dynasty.Their main arguments are Luo Guanzhong's life materials and the comments on small character of The Romance of the Three Kingdoms.Du Guichen trys to expound that it was written in the Yuan dynasty according to Quyou's words and Zhangxian's poems.In fact,Mr Du's views are wrong.
