Perhaps you should try some spelling variations:
luan nhung » luan chung, luan hung, quan nhung
hanh dung » thanh dung, anh dung, hanh dong
ho chieu » theo chieu, hoc thieu, doi chieu
theo chu » theo chieu, cho chu, chao chu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan tap » toan ban

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