Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
canh tran » canh tranh, hanh trang, banh trang
bang cong » dang cong, bang song, hang cong
theo chu » theo chieu, chao chu, theo yeu
tran van » luan van
dan phan » doan phan, dan chan, van phan
phan cac » nhan cach, phan dau, phan lap
cho chu » cho thue

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: ((theo chu) OR (cho chu)) sang - canh tran van ((nhung cong) OR (bang cong)) dan phan cac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) sang - canh tran van ((nhung cong) or (bang cong)) dan phan cac~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) sang - canh tran van ((nhung cong) or (bang cong)) dan phan cac*.
