Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, nhung don
mot trieu » mot chieu, mot tri, mon triet
trung cam » trung tam, trung cap, trung nam
hang cong » dang cong, hang nong, bang cong
khan cap » khan ap, khoan cam, phan cac
than cap » thanh lap, thanh cac, than cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: mot trieu tinh - thanh trung cam ((nhung cong) OR (hang cong)) san ((khan cap) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "mot trieu tinh - thanh trung cam ((nhung cong) or (hang cong)) san ((khan cap) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: mot trieu tinh - thanh trung cam ((nhung cong) or (hang cong)) san ((khan cap) OR (than cap))*.
