Perhaps you should try some spelling variations:
nhung tri » nhung bai, dung tri, nhung bi
nhung loi » nhung bai, nhung bi, nhung gi
biet tran » bien tran, viet tran, viet trang
trong san » trong cac, dong san, trong ca
cong san » cong tac
que van » quy van, quyet van, quan van
qua van » quan van, qua ban, qua san

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((nhung tri) or (nhung loi)) ((que van) OR (qua van)). biet tran ((trong san) or (cong san)) thanh~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((nhung tri) OR (nhung loi)) ((que van) OR (qua van)). biet tran ((trong san) OR (cong san)) thanh.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nhung tri) or (nhung loi)) ((que van) OR (qua van)). biet tran ((trong san) or (cong san)) thanh".
• Adding a wildcard symbol may retrieve word variants: ((nhung tri) or (nhung loi)) ((que van) OR (qua van)). biet tran ((trong san) or (cong san)) thanh*.
