Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
doi chieu » doc hieu, doi chi, mot chieu
tranh van » trinh van, thanh van, tranh ban
cong doan » cong dan, cong hoan, dong doanh
doan phan » doanh phan, toan phan, dan phan
ho chieu » theo chieu, hoc thieu, mot chieu
tran van » luan van
phan cau » phan dau, phan cac, phan tu

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 - canh ((tranh van) OR (tran van)) nhung cong doan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (doi chieu)) xanh - canh ((tranh van) or (tran van)) nhung cong doan phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (doi chieu)) xanh - canh ((tranh van) or (tran van)) nhung cong doan phan cau*.
