Is black and white impermanence one black and one white?
Black and white impermanence is not due to the difference of skin color or clothing color, but is called black impermanence and white impermanence. The impermanence of black and white is only the representation of yin and yang, and "black" and "white" represent one yin and one yang. In other words, black impermanence represents feminine body, while white impermanence represents masculine body. This is also consistent with the contrast diagram of black and white = the color of yin and yang fish in Taiji diagram.
When did black and white impermanence come?
In the Qing Dynasty, "Jade Calendar Treasures" began to spread among the people. It is said that in this book, there are images of black impermanence and white impermanence. But this was written by Mr. Lu Xun in his article. As for the illustrated book "Jade Calendar Treasure" he saw, I don't know when it was painted. Therefore, it can be roughly inferred that black-and-white impermanence originated from the Qing Dynasty to the Republic of China and should not be earlier than the Yuan and Ming Dynasties.
