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
cua dung » cua dong, qua dung, cua rung
cua dang » cua cong, cua ban
cong tan » cong tac, cong san, cong thanh
tan chan » dan chan, ban chan, can chan

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) OR (cua dang)) cong tan 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) OR (cua dang)) cong tan chan soan~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (trieu tinh)) - thanh tung ((cua dung) OR (cua dang)) cong tan chan soan*.
