Do domestic calligraphers have national certified works value certificates?

No, it is also difficult to join the China Calligraphers Association. It may be possible if your work can participate in a national exhibition and win a grand prize. There are many "tricks" in the awards, which are very complicated. Unless your works are valued by famous artists and you have everyone's level, you have a bright future. If you want to buy a "member", you need about 1.5 million silver now. The prices of general works are estimated by the so-called "experts" of auction companies, so that buyers can have a reference. It is really necessary for both sides to negotiate again. At present, there are few good calligraphy in the true sense, and even fewer can write verve. The museum's collections will not be sold, and the folk ones belong to the nature of "market economy".
