Perhaps you should try some spelling variations:
chua xang » chua nang, chuc nang, chu bang
dung cong » dung trong
chu xanh » chu manh, chieu xanh, chuc danh
tranh va » tranh van, trang va, trinh va
cong tan » cong tac, cong san, cong thanh
tran cau » tran chau, ran cau, tra cau
toan cau » toan cao, toan ban, toan tap
va dung » van dung, va duong, vat dung

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