Xidan Joy City is a big business district in Beijing. There are many famous old shopping malls nearby, and the consumption level near Tiananmen Square is very high.
Sanlitun Taikooli has many fashion landmarks with "first" and "only" titles, and it is a comprehensive place with the highest consumption level in Beijing. So I like fashion petty bourgeoisie and shop in Sanlitun. I prefer shopping in downtown and Xidan Joy City.
