Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
luan hang » luan nang, luan han, luan tang
luan hung » luan chung, lan hung, luan ung
theo chu » theo chieu, cho chu, chao chu
chu xanh » chu manh, chieu xanh, chua xang
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

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