Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh van » trinh han, trinh quan, trinh toan
tranh cac » trinh cac, thanh cac, tranh cai
ban cong » bang cong, van cong, phan cong
cong tac » cong ty
tran cao » tran chau, trang cho, tranh cai
toan cao » toan ban, toan tap
cho chu » cho thue
chu van » cuu van, chu han

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: cho chu van - hanh trinh van ban cong tac ((((tran cao) OR (tranh cac))) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: cho chu van - hanh trinh van ban cong tac ((((tran cao) or (tranh cac))) or (toan cao))*.
