When I graduated in 1998, Yongtai Community (in Qinghe, Haidian District) next to the school was said by my classmates to be 2 100 yuan per square meter. At that time, there were few commercial houses and the loan conditions were very harsh. Generally, people who have to be demolished at home can buy a house.

1999 I work in Zhongguancun Third Bridge (a bridge on the North Fourth Ring Road). Shuiqingmu Garden Community is under construction, and the opening pre-sale price starts from 4,900 yuan.
