Senior calligrapher ~ calligrapher Gao and Gao Guozhi's father's senior calligraphy, the latest price, how much is it per square meter?

Gao-Gao Yang Gao's painters and calligraphers are sold in many art networks and physical stores, with about 5 million square meters and about 500,000 square meters of calligraphy (high brown calligraphy). Gao's father's powerful calligraphers are generally not sold in the high-end market. He is good friends with Gao Guanmen (selected as one of the four gifted scholars in China with Ouyang). Generally speaking, the high friend relationship is about 20. 1 10,000 square meters, but his calligraphy is not in circulation in the market, and the price is hard to say. How much the price depends on his fate and love relationship with his works. In short, the high price of works is very transparent, because it is not for sale, and it is difficult for his father to evaluate the price. It's about that price, so I can't say for sure.
