In practice Yu shows the characteristics of his own exegesis characteristics:being able to make new findings, paying attention to contemporary scholars'thoughts, and holding truth even confronting his teachers. Compared with former or contemporary exegetic experts, Yu's exegeses puts more emphasis on supplementing historical facts and explaining words'meanings.
