Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, mot chieu
manh hung » anh huong
dai nhung » ai nhung, dai khung, dap nhung
ho chieu » theo chieu, hoc thieu, mot chieu
hung dai » hung dao, hung dam, hung dan
cong san » cong tac
toan ban » van ban

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 (doi chieu)) xanh - manh hung dai nhung cong san ((toan tap) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi chieu)) xanh - manh hung dai nhung cong san ((toan tap) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chieu)) xanh - manh hung dai nhung cong san ((toan tap) OR (toan ban))*.
