How much is Wu's handwriting a foot?

Wu is one of only two calligraphers among the national Olympic torchbearers. It is said that the national calligraphers rank in the top ten. Three years ago, his work was 12300 yuan a foot, but in recent years, he wrote less, so the price went up. These works are worthless. The key depends on whether there is his seal. If there is no seal, the value is small. Having his seal on it is a guarantee of value. At present, some painting and calligraphy institutes in Beijing sell Wu's calligraphy, and the price is over 100,000 yuan, which is extremely rare. I have seen one, and the collector asked for 60 thousand. Things are rare, and the less Wu writes, the less works and the higher the value. Another one was painted by Wu, with an estimated value of 40,000 yuan. I have the honor of collecting it. In recent years, fewer people pay attention to calligraphy, and there are several great calligraphers, which are rarely seen in public.
