Perhaps you should try some spelling variations:

hoc thieu » toc thieu, hoc hien
van cuong » van chuong, van duong, van cong
ho chieu » theo chieu, doi chieu, mot chieu
tran van » luan van
cong ban » cong bang, cong san, cong dan
cong tan » cong tac, cong san, cong thanh
khan cap » khan ap, than cap, khoan cam

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 tran van cuong ((cong ban) OR (cong tan)) khan cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) xanh - thanh tran van cuong ((cong ban) OR (cong tan)) khan cap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) xanh - thanh tran van cuong ((cong ban) OR (cong tan)) khan cap*.
