Will Africans turn white after living in China for 20 years?

Africans will not turn white after living in China for 20 years, because their skin color is determined by genes.

The color of skin depends on the pigment under the skin, also called skin pigment, one of which is called melanin, which can reduce the harm of ultraviolet rays to human body. Africans near the equator have been exposed to strong ultraviolet rays for generations. In order to reduce the damage of ultraviolet rays to the skin, we can only secrete more melanin to protect the skin, which is the result of natural evolution.

Sub-Saharan Africa, commonly known as black Africa, is an authentic black carbon, especially the black ethnic group near the equator, which is the main source of black people all over the world, and the indigenous ethnic group in Australia is also black.
