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 nang, luan han, luan hung
hang cong » dang cong, hang nong, bang cong
chu xanh » chu manh, chieu xanh, chuc danh
cong anh » cong danh, dong anh, hong anh
toan cao » toan ban, toan tap

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