Perhaps you should try some spelling variations:
nhieu tang » chieu sang, hieu lang, nhiet nang
hop nhieu » hoc thieu, ho chieu, he nhieu
trung cua » truong cua, trung tuan, dung cua
trung cap » truong cao, trung tam
cong san » cong tac
san than » sang than, san thanh, ban than
than cap » khan cap, thanh lap, thanh cac

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "hop nhieu tang - thanh ((trung cua) OR (trung cap)) trong cong san than cap~".
• Adding a wildcard symbol may retrieve word variants: hop nhieu tang - thanh ((trung cua) OR (trung cap)) trong cong san than cap*.
