Perhaps you should try some spelling variations:
trinh quan » tinh quang, trinh luat, trinh han
hanh trinh » canh tranh, hanh chinh
tieu danh » dieu danh, thien danh, dieu hanh
tiep danh » thien danh, tiep can, hiep dinh
quan cong » qua cong, luan cong, quan dong
nong dan » cong dan, nong san, nguong dan
cong san » cong tac
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: theo ((tieu danh) OR (tiep danh)) - hanh trinh quan cong ((nong dan) OR (cong san)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu danh) OR (tiep danh)) - hanh trinh quan cong ((nong dan) or (cong san)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu danh) OR (tiep danh)) - hanh trinh quan cong ((nong dan) or (cong san)) toan tap*.
