Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
tieu danh » dieu danh, tiep danh, thien danh
trinh thi » trinh tai, dinh thi, trinh tu
thi thong » thi thuong, thi hong, thi khong
cuong tap » luong tap, luong tai, cong tan
cong tac » cong ty
toan cao » toan tap
toan ban » van 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 - hanh trinh thi thong ((cong tac) OR (cuong tap)) ((toan cao) OR (toan ban))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu danh - hanh trinh thi thong ((cong tac) or (cuong tap)) ((toan cao) OR (toan ban))~".
• Adding a wildcard symbol may retrieve word variants: theo tieu danh - hanh trinh thi thong ((cong tac) or (cuong tap)) ((toan cao) OR (toan ban))*.
