Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
nhung cong » dung cong, thong cong, hang cong
trung hoc » trung quoc
ho chieu » theo chieu, hoc thieu, doi chieu
trung ha » trung tam, trung cap
cong dan » cong san, cong tan, huong dan
phan cau » phan dau, phan cac, phan lap

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