Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
thanh tung » thanh cong
chan soan » chan doan, han san, ban soan
tung cua » trung cua, tuong cua, dung cua
cua dung » cua dang, cua dong, qua dung
cong tan » cong tac, cong thanh, cong ty
cong san » cong tac

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: ho ((chieu tinh) OR (trieu tinh)) - thanh tung cua dung ((cong tan) OR (cong san)) chan soan~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (trieu tinh)) - thanh tung cua dung ((cong tan) OR (cong san)) chan soan~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - thanh tung cua dung ((cong tan) OR (cong san)) chan soan*.
