Perhaps you should try some spelling variations:
hanh trinh » canh tranh
chua xang » chua nang, chuc nang, chu bang
quan dung » quang dung, quan duong, qua dung
dung cong » dung trong
chu xanh » chu manh, chieu xanh, chuc danh
cong tan » cong tac, cong san, cong thanh
tan san » tai san, tan van, han san
san cau » van cau, ban cau, can cau

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: cho ((chu xanh) OR (chua xang)) - ((hanh trinh) OR (hanh chinh)) quan dung cong tan san cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cho ((chu xanh) OR (chua xang)) - ((hanh trinh) or (hanh chinh)) quan dung cong tan san cau~".
• Adding a wildcard symbol may retrieve word variants: cho ((chu xanh) OR (chua xang)) - ((hanh trinh) or (hanh chinh)) quan dung cong tan san cau*.
