《谷梁传》通过“存其同而求其所以异”、“略小异而求大同”等方法,对《春秋》的书法义例作了大量的阐发。《谷梁传》在说解逻辑上还比较粗疏,不严格,且常有互相矛盾的地方。《谷梁传》所阐发的书法,在某种程度上还只是一些有待探明的意义标识符号。 “Gu Liang Chuan” made a great deal of elucidation on the calligraphic cases of “Spring and Autumn” through such methods as “keeping the same with the same, seeking different reasons” and “seeking common ground with small differences”. “Gu Liang Chuan” in the solution to the logic is still relatively loose, not strict, and often contradictory. Calligraphy elaborated in Gu Liang Chuan is, to some extent, only some sign of significance that needs to be proved.
