Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, kieu tinh
truong cao » truong dai
nhung cong » dung cong, thong cong, hang cong
chau tinh » cuu tinh, ha tinh, cua tinh
trung hoc » trung quoc
cong dan » cong san, cong tan, huong dan
dan phan » doan phan, dan chan, van phan
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: doi ((chieu tinh) OR (chau tinh)) - hanh ((trung hoc) OR (truong cao)) nhung cong dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((chieu tinh) OR (chau tinh)) - hanh ((trung hoc) or (truong cao)) nhung cong dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((chieu tinh) OR (chau tinh)) - hanh ((trung hoc) or (truong cao)) nhung cong dan phan cau*.
