Is the painting and calligraphy taken by Zhenmotang Mo Chi Painting and Calligraphy Institute authentic or imitation?

The paintings and calligraphy taken by Zhenmotang Mo Chi Painting and Calligraphy Institute are imitations. At present, there are few original paintings before the Song Dynasty in the museum. What we can see now, such as Gu Kaizhi, Li Sixun, Zhang Xuan and Zhou Fang, are basically copied by later generations, that is, imitated. But now these imitations are equally valuable and still national treasures. In modern times, Zhang Daqian's copying of Shi Tao and the paintings of the Eighth National Congress can also be confused with the truth, but he is still an original of Zhang Daqian and still has great value. In fact, copying is a step in learning Chinese painting. All China painters basically copy ancient paintings, and most of them have good cultural accomplishment, aiming at learning pen and ink. So imitation is not necessarily bad, there are good and bad, it depends on your eyes.
