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

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 tung cam ((nhung cong) OR (hang cong)) san ((khan cap) OR (khan ap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "mot trieu tinh - thanh tung cam ((nhung cong) or (hang cong)) san ((khan cap) OR (khan ap))~".
• Adding a wildcard symbol may retrieve word variants: mot trieu tinh - thanh tung cam ((nhung cong) or (hang cong)) san ((khan cap) OR (khan ap))*.
