Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong tan, huong dan, cong dong
cong san » cong tac
than cau » toan cau, phan cau, than cap
tinh va » tich va, trinh van, trinh vat
anh va » hanh va

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu tinh - canh ((anh va) or (tinh va)) dung ((cong dan) OR (cong san)) than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - canh ((anh va) OR (tinh va)) dung ((cong dan) OR (cong san)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - canh ((anh va) or (tinh va)) dung ((cong dan) OR (cong san)) than cau".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - canh ((anh va) or (tinh va)) dung ((cong dan) OR (cong san)) than cau*.
