Perhaps you should try some spelling variations:
theo chieu » theo tieu, theo chu, thi chieu
thanh tung » thanh cong
ho chieu » hoc thieu, doi chieu, mot chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
tung va » trung va, tuong va, dung va
thi cao » thai cao, thi hao, thi bao

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) OR (theo chieu)) xanh - thanh tung va thuong ((cong dan) OR (cong tan)) thi cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - thanh tung va thuong ((cong dan) OR (cong tan)) thi cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - thanh tung va thuong ((cong dan) OR (cong tan)) thi cao*.
