Ask the teacher, the inscription of this word was given by a friend. Take it home for the children to play with. Is there any remedy? Is there any remedial value?

You asked about the autograph, but you didn't take all the autograph parts. I only vaguely see the word "Banqiao". Yin and Yang seal, the poem is "Wang Cao? The main entrance ",Yang Wen" Wang Yin ". The handwriting is ok, and the running script smells like Li. Inscription "Banqiao ..." Did you write Zheng Banqiao? Isn't the style very similar? Calligraphy works talk about the artistic value of the font itself; Second, whether the lecture is long and whether the author is famous; Three lectures on the appearance of objects. To sum up, there is no preservation value. However, as a friend's gift, it has its extra significance. Think for yourself whether you are kind or not.
