Perhaps you should try some spelling variations:
thuong va » truong va, thong va, thuong mai
tong cong » trong cong, cong cong, dung cong
chi tach » chiu trach, chiet tach, chi thanh
huong va » luong va, duong va, muong va
cong tan » cong tac, cong san, cong thanh
tan than » tan thanh, tan tran, ban than
than cao » toan cao, thai cao, than cap
doi chi » doi khi

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