How many years has Chinese painting been called "Chinese painting"?

This is the same as the method adopted by our country. In ancient times, the concept of "China" was relatively general, but people didn't have this concept at that time. For example, there is a famous historical monograph "Fifteen Years of Wanli", in which the fifteenth year of Wanli is AD 1587, which was calculated by our modern historians through time deduction, with the purpose of putting the history of China on the coordinate axis of time for in-depth observation! In ancient times, China was an agricultural country. It can be said that agriculture is the foundation of the country. Therefore, the emperor promulgated the Gregorian calendar at the beginning of the new year every year. First of all, he reminded people of the exact time of the 24 solar terms and let them farm. The second is time, such as 55 years.

Chinese painting, that is, "Chinese painting", also puts China's art on the coordinate axis of time for in-depth observation, which should be after the founding of the People's Republic of China.
