Perhaps you should try some spelling variations:
phuong cong » phuong dong, phong cong, phung cong
cuu phuong » cac phuong, thu phuong
doi chieu » doi chi, ho chieu, mot chieu
nhan dinh » nhan sinh, phan dinh, nhan tinh
doc hieu » toc thieu, hoc thieu, hoc hien
dinh cuu » dinh chi
cong dan » cong san, cong tan, huong dan
cac cau » cac mau, ca cau, cac cam
bac cau » bach cau, ba cau, bac can

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: ((doi chieu) OR (doc hieu)) xanh - nhan dinh cuu phuong cong dan ((cac cau) OR (bac cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((doi chieu) or (doc hieu)) xanh - nhan dinh cuu phuong cong dan ((cac cau) OR (bac cau))~".
• Adding a wildcard symbol may retrieve word variants: ((doi chieu) or (doc hieu)) xanh - nhan dinh cuu phuong cong dan ((cac cau) OR (bac cau))*.
