I don’t know much about Mr. Zhou Botao’s calligraphy, but the price of calligraphy varies. Some time ago, due to work needs, I asked Mr. Fu Jianzeng to inscribe the calligraphy, and the price was about 5,000 per square foot. This gentleman's calligraphy style is very unique and he is good at cursive calligraphy, especially left-hand calligraphy. He is the current vice president of the Chinese Calligraphers and Painters Association. You can contact us to find out more details
