Li Tian asked the staff: I want to ask a more professional question, this question has plagued me for many years, that is, is the zebra black on white background, or white stripe black background?
Staff: In fact, when the zebra is in the embryo, it grows black hair first, so the zebra is an animal with white stripes on a black background.
Li Tian: Got it, I learned it today.
Li Tian will also be interested in such a professional problem, it is really rare, I often see his program, very funny and eloquent is also very good, but some people say that he is more than two, do not know what is in reality, there may also be more than two in the program, in life is not like that.
