2) Many of these people's works sold in galleries in Beijing Liulichang and other places are fakes, mostly written by disciples.
3) Personally, if you don't know these famous artists, there is only one method with the least risk and the highest cost performance, and that is to go to the training center of China Book Association and ask the teachers there to help you contact, so that you can get the real original works of famous artists at affordable prices.
Address: Calligraphy Training Center of China Calligraphers Association, Wanshou Road 17, Haidian District, Beijing.
The teachers there are simple, enthusiastic and helpful. One of them is Mr Liu Wenhua, who is a disciple of Mr Liu Bingsen. I personally bought Mr Ouyang Zhongshi's original works for my friends in this way. Suggest that friends who ask questions may wish to give it a try.
