Perhaps you should try some spelling variations:
thanh trung » thanh tung
hoc thieu » toc thieu, hoc hien
trung cac » truong cac, trung cap, trong cac
ho chieu » theo chieu, doi chieu, mot chieu
cac dang » cao dang, cac dan, cac cong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
toan cao » toan ban, toan tap

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 (hoc thieu)) xanh - thanh trung cac dang ((cong tan) OR (cong tac)) toan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - thanh trung cac dang ((cong tan) or (cong tac)) toan cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - thanh trung cac dang ((cong tan) or (cong tac)) toan cao*.
