Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, thong cong, hang cong
trinh ve » trinh he, trinh va, trinh vi
ve nhung » va nhung, tu nhung
cong dan » cong san, cong tan, huong dan
toan cau » toan ban, toan tap
toan tai » toan tap, doanh tai, toan ban
toan cao » toan ban, toan tap
so cuu » so huu, ho cuu, so cau

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: so cuu tinh - hanh trinh ve nhung cong dan ((((toan cau) OR (toan tai))) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: so cuu tinh - hanh trinh ve nhung cong dan ((((toan cau) or (toan tai))) or (toan cao))*.
