Why can't the words written by the master of national ceremony be sold?

the handwriting written by the master of national ceremony cannot be sold because it is not calligraphy.

Most of them are Jianghu calligraphy gangsters. Therefore, the words written by the master of national ceremony cannot be sold because they are not calligraphy.
