Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
chu tinh » chau tinh, chua tinh, cuu tinh
trinh va » trinh van, trinh vat, trinh ve
cong tac » cong ty
cong tan » cong thanh, cong ty, cong ha
toan ban » van ban
ho chu » hoi chu, cho chu, ho chua

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: ho chu tinh - hanh trinh va nhung ((((cong tac) OR (cong san))) OR (cong tan)) toan ban~.
• Adding a wildcard symbol may retrieve word variants: ho chu tinh - hanh trinh va nhung ((((cong tac) or (cong san))) or (cong tan)) toan ban*.
