Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, thong cong, nhung don
hoc thieu » toc thieu, hoc hien
thi chieu » thi chien, thi hieu, theo chieu
trinh van » trinh han, trinh quan, trinh toan
hang cong » dang cong, hang nong, bang cong
van van » tan van, san van, van vat

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: ((hoc thieu) OR (thi chieu)) xanh - hanh trinh van ((nhung cong) OR (hang cong)) van van ban~.
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) or (thi chieu)) xanh - hanh trinh van ((nhung cong) or (hang cong)) van van ban*.
