What is the value of Qian Facheng's calligraphy collection?

Qian Facheng's calligraphy skill is far better than that of the vice chairman of Zhejiang Book Association. Traditional culture has a solid foundation, and poetry couplets are good! Because I have been a cultural director, I am very low-key and cautious. Unlike some calligraphers, they will speculate! With his knowledge and historical events, it is far from the current price to speculate!
