What is the price of calligraphy in Li Duo?

According to the rules of calligraphy and painting works, it is estimated that each square foot is more than 5000 yuan; If it is an ordinary work, the appearance and content are not ideal, and the price is low. Personally, I like Mr. Li Duo's calligraphy very much. Recently, I spent 18000 on one of his paintings, which is 4 feet and 8 square meters, hehe. I also spent 12000 to buy three-foot couplets and six-foot couplets. It feels great! !
