Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
chau tinh » cuu tinh, ha tinh, cua tinh
trinh van » trinh han, trinh quan, trinh toan
dung cong » dung trong
van dung » van dong, xay dung, tin dung
cong dan » cong san, cong tan, huong dan
toan cau » toan cao, toan tap
toan tai » toan tap, doanh tai, toan cao
toan ban » van ban
o chau » a chau, 3 chau, moc chau

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: o chau tinh - hanh trinh van dung cong dan ((((toan cau) OR (toan tai))) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: o chau tinh - hanh trinh van dung cong dan ((((toan cau) or (toan tai))) or (toan ban))*.
