Is Niu Hongchang's heavenly reward valuable?

Worth some money. Niu Hongchang, 1963 was born in Nangong City, Hebei Province. He inherited his family studies since childhood, was influenced by his father, and loved painting and calligraphy. His work "Heaven rewards diligence" can be purchased on the online shopping platform, with an average price of 1500 to 2,000 yuan, which is relatively valuable. Niu Hongchang focused on the Erwu cursive script. During my stay at China Calligraphy Correspondence University, I was fortunate to be guided by teachers such as Shen Peng, Sun Boxiang and Li Duo, and gradually integrated the essence of Weibei, Ou Kai and Nangong Monuments.
