Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
luan nhung » luan chung, luan hung, quan nhung
hanh tung » thanh tung, manh tung, hanh dung
ho chieu » theo chieu, hoc thieu, doi chieu
anh bang » anh hoang, anh quang, tinh bang
cong tan » cong tac, cong san, cong thanh
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: ho chieu xanh - ((hanh tung) OR (anh bang)) luan nhung ((cong tan) OR (cong ty)) toan cao~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - ((hanh tung) or (anh bang)) luan nhung ((cong tan) or (cong ty)) toan cao*.
