Can't calligraphy be signed for art exhibitions?

It depends on what kind of game it is. Some competitions are anonymous to prevent some judges from taking advantage of their rights.

If we only look at the quality of works, I believe that the calligraphy of many celebrities and the calligraphy of the so-called chairman and director will be discredited in Sun Shan, and no one will pay attention to it. Many unknown people will stand out because of their solid foundation and really good handwriting. Whether Chinese characters can last forever lies not in hype, but in structure, brushwork and a series of inherent skills of calligraphy itself.
