Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
hanh dung » thanh dung, anh dung, hanh dong
luan hang » luan han, luan hung, luan tang
luan nang » luan van, van nang, luan san
chu xanh » chu manh, chieu xanh, chuc danh
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan tap » toan ban

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 xanh) OR (chua xang)) - hanh dung ((luan hang) OR (luan nang)) cong san toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chu xanh) or (chua xang)) - hanh dung ((luan hang) OR (luan nang)) cong san toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((chu xanh) or (chua xang)) - hanh dung ((luan hang) OR (luan nang)) cong san toan tap*.
