Is Nan's calligraphy valuable?

Nan's calligraphy is very valuable. Nan's works fetched a high price of 560,000 yuan at the 20 18 Hong Kong calligraphy auction. Nan, male, was born in 1957, from Xinjiang, Shaanxi. Influenced by my parents, I have loved painting and calligraphy since I was a child. I started with the mysterious pagoda in Liu Gongquan. Later, I had a special liking for Jiucheng Palace and Huangfu Birthday Monument in Ou Yangxun. I have worked hard and never stopped, and I have achieved fruitful results for decades. Later, I also studied many pagodas in Yan Zhenqing.
