There is no reason to doubt tradition. If it must be associated with tradition, there is a saying in Hanshu that "wandering" is today's "wandering". The brushwork of "Gone with the Wind" in Su Shi's calligraphy works of Red Cliff Fu is "Pei"; The word "wandering" in Huang Daozhou's running script "Poems of Qin Qiu Er Yun" is the same as that written by Su Shi. Therefore, in the application of calligraphy works, the wandering tradition can be replaced by "wandering back" or "wandering back", and can also be applied to seal script or seal cutting.
