Perhaps you should try some spelling variations:
truong cao » truong dai
chau tinh » cuu tinh, ha tinh, cua tinh
trung ha » trung hoc, trung tam, trung cap
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
toan tap » toan ban
ho chau » ha chau, ho chu, o chau

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 chau tinh - hanh ((trung ha) OR (truong cao)) nhung ((cong dan) OR (cong tan)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chau tinh - hanh ((trung ha) or (truong cao)) nhung ((cong dan) OR (cong tan)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chau tinh - hanh ((trung ha) or (truong cao)) nhung ((cong dan) OR (cong tan)) toan tap*.
