Perhaps you should try some spelling variations:
thanh thuong » thanh huong, thanh chuong, thanh phuong
thanh tuong » thanh tung, thanh huong, thanh cuong
dung cong » dung trong
chi tach » chiu trach, chiet tach, chi thanh
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, va duong, vat dung

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: "doi chi tach - ((thanh tuong) OR (thanh thuong)) va dung cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chi tach - ((thanh tuong) OR (thanh thuong)) va dung cong tan toan cao*.
