Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
thanh tuong » thanh tung, thanh huong, thanh cuong
chi tach » chiu trach, chiet tach, chi thanh
va duong » van duong, va tuong, va huong
cong tan » cong tac, cong san, cong thanh
tan toan » tan tran, tap toan, van toan
toan cao » toan ban, toan tap
doi chi » doi khi
va dung » van dung, vat dung, va ung

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: doi chi tach - ((thanh tuong) OR (thanh thuong)) ((va dung) OR (va duong)) cong tan toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chi tach - ((thanh tuong) or (thanh thuong)) ((va dung) OR (va duong)) cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chi tach - ((thanh tuong) or (thanh thuong)) ((va dung) OR (va duong)) cong tan toan cao*.
