Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
hieu nganh » vien nganh, hiem ngan, nghiep nganh
phuong dan » phuong danh, phuong doan, huong dan
hieu manh » chieu xanh, dieu hanh, hien hanh
canh dinh » canh tinh, anh dinh, canh binh
van nhung » van nhuong, va nhung, van hung
dan van » dang van, doan van, dao van

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: doc ((hieu nganh) OR (hieu manh)) - canh dinh van nhung phuong dan van ban~.
• Adding a wildcard symbol may retrieve word variants: doc ((hieu nganh) or (hieu manh)) - canh dinh van nhung phuong dan van ban*.
