Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
hanh dung » thanh dung, anh dung, hanh dong
luan dung » lan dung, luan dong, luan hung
dung cong » dung trong
chu xanh » chu manh, chua xang, chuc danh
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
chu han » chu van

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 (chieu xanh))) OR (chu han)) - hanh dung luan dung cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chu xanh) or (chieu xanh))) or (chu han)) - hanh dung luan dung cong dan toan cau*.
