introduction for myself I am a 26-years old、chinese boy(man), working as a data analyst, my major when i am in the university is statistics and probability theory, I like sports or doing some incentive things, my favorate sport used to be football, but it changed when i begin to wear glasses, now I usually swim or play badminton. chinese is a country with the largest population in the world and the third largest territory(I learn it from the textbook of middle school), chinese culture is complicated, there are different customs between north and south, east and west, from province to province, city to city, it really need a long time to have a sense about it.
