Perhaps you should try some spelling variations:
hanh dung » thanh dung, anh dung, hanh dong
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, cong dong
toan tai » toan tap, doanh tai, toan ban
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 - hanh dung luan hung ((cong dan) OR (huong dan)) ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh dung luan hung ((cong dan) or (huong dan)) ((toan tai) or (toan cao))*.
