Perhaps you should try some spelling variations:
chinh cong » thanh cong, trinh cong
hanh trinh » canh tranh, hanh chinh
theo chau » theo chu, theo chieu, theo phap
chau tinh » cuu tinh, ha tinh, cua tinh
trinh han » trinh quan
han chinh » hanh chinh, hoan chinh, hang chinh
cong dan » cong san, cong tan, huong dan
toan tai » toan tap, doanh tai, toan ban
toan cao » toan ban, toan tap

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 chau tinh - hanh trinh han chinh cong dan ((toan tai) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: theo chau tinh - hanh trinh han chinh cong dan ((toan tai) or (toan cao))*.
