The price of calligraphy and painting works of art is a matter of concern to everyone

Some people have asked about his paintings before, but these cannot be directly priced because there are many aspects to consider in calligraphy and painting works of art. It is unscientific to evaluate the price of the work from many aspects such as the exquisiteness of the work, the theme of the work, the social influence of the work, the age of the work, the size of the work, etc. It is unscientific to set the price in a general way! Do you think it makes sense?
