Introduction to Wangyue Building: Wangyue Building integrates special Chinese food, tea tasting, leisure, entertainment and other functions. There are two big yellow kudzu trees in front of the building. The green lawn between the two trees is a sewage treatment tank. The national key environmental protection technology "micro-exposure oxidation ditch circulating SBR method" and "solar radiation denitrification method" are combined to purify and treat domestic sewage in the panoramic area.
