Perhaps you should try some spelling variations:
thanh tran » thanh trang, thanh toan, thanh tra
tran thanh » van thanh, quan thanh
nhung don » nhung van, nhung bo
hang cong » dang cong, hang nong, bang cong
ban thanh » ban hanh, ban hang
thanh cau » thanh chau, thanh mau, nhanh cau
doc hieu » toc thieu, hoc thieu

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: ((doc hieu) OR (hoc hien)) xanh - thanh tran thanh ((nhung don) OR (hang cong)) ban thanh cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doc hieu) OR (hoc hien)) xanh - thanh tran thanh ((nhung don) or (hang cong)) ban thanh cau~".
• Adding a wildcard symbol may retrieve word variants: ((doc hieu) OR (hoc hien)) xanh - thanh tran thanh ((nhung don) or (hang cong)) ban thanh cau*.
