Ma Xijing, a native of Henan, is a member of Dunhuang Creation Center of China Artists Association, and the executive director of China Painting Art Research Institute and China Calligraphy Art Research Institute.
Wang xijing, a native of Xi, is currently a director of China Artists Association, vice chairman of Shaanxi Federation of Literary and Art Circles, president of Xi China Painting Academy and chairman of Xi Artists Association.
At present, the calligraphy market is not prosperous, mainly because some famous, low-level and hyped "calligraphers" have messed up.
If it is Ma Xijing's original, this four-foot-long character is still very collectible. However, the calligraphy market is not good at hype, and the price can't go up now. I suggest that you don't sell it. It's better to collect it and sell it at the right time.
If it is an original Ma Xijing, it can be sold for one or two thousand yuan now.
