Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
toan thanh » tran thanh, hoan thanh, toan thang
thanh bang » thanh hang, thanh ban, thanh hoang
ho chieu » theo chieu, hoc thieu, doi chieu
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cau » toan cau, than cap, thanh chau
phan cau » phan dau, phan cac, phan tu

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 - tinh toan thanh bang ((cong dan) OR (cong tan)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - tinh toan thanh bang ((cong dan) or (cong tan)) ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - tinh toan thanh bang ((cong dan) or (cong tan)) ((than cau) OR (phan cau))*.
