Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
nhung cong » dung cong, thong cong, hang cong
trinh va » trinh van, trinh vat, trinh ve
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
ho cuu » ho chu, ho cua, so cuu

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 cuu tinh - hanh trinh va nhung cong dan ((((toan cau) OR (toan tai))) OR (toan cao))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho cuu tinh - hanh trinh va nhung cong dan ((((toan cau) OR (toan tai))) or (toan cao))~".
• Adding a wildcard symbol may retrieve word variants: ho cuu tinh - hanh trinh va nhung cong dan ((((toan cau) OR (toan tai))) or (toan cao))*.
