Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
theo chieu » theo tieu, ho chieu, theo chu
trinh cua » tinh cua, trinh luat, trinh quan
cua nhung » va nhung
cong dan » cong san, cong tan, cong dong
toan cao » toan ban, toan tap
doi chi » doi khi

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