Perhaps you should try some spelling variations:
chieu tinh » lieu tinh, chau tinh, kieu tinh
hanh trinh » canh tranh, hanh chinh
trinh van » trinh han, trinh quan, trinh toan
van dung » van dong, xay dung, tin dung
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
toan cau » 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: ho ((chieu tinh) OR (trieu tinh)) - hanh trinh van dung ((cong dan) OR (cong san)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) OR (trieu tinh)) - hanh trinh van dung ((cong dan) or (cong san)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) OR (trieu tinh)) - hanh trinh van dung ((cong dan) or (cong san)) toan cau*.
