Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
luan nang » luan van, van nang, luan san
nang cong » nang song, dang cong, bang cong
theo chu » theo chieu, chao chu, theo yeu
dan toan » van toan, manh toan, xuan toan
dan than » dan chan, ban than, van than
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)) xanh - hanh dung luan nang cong ((dan toan) OR (dan than)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chu) OR (cho chu)) xanh - hanh dung luan nang cong ((dan toan) or (dan than)) tap~".
• Adding a wildcard symbol may retrieve word variants: ((theo chu) OR (cho chu)) xanh - hanh dung luan nang cong ((dan toan) or (dan than)) tap*.
