Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh cua » tinh cua, trinh luat, trinh quan
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cao » toan cao, thai cao, than cap

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 (doi khi)) xanh - hanh trinh cua nhung ((cong dan) OR (cong san)) than cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (doi khi)) xanh - hanh trinh cua nhung ((cong dan) OR (cong san)) than cao~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi khi)) xanh - hanh trinh cua nhung ((cong dan) OR (cong san)) than cao*.
