What's Zhihu's experience with black people?

Black people and people in some countries that usually live in Africa are born with black skin. China people, as descendants of China people, China people are mostly yellow-skinned. Standing with black people, our skin will certainly be better, brighter and more beautiful, but black people have big eyes, big mouths and darker eyes. Wu Liang's teeth are whiter and more energetic, but they are far less beautiful and confident than those in China.
