Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
trung tuan » trung thanh, trung tam, tran tuan
cong thanh » dong thanh, cong trinh, truong thanh
doi chieu » doc hieu, doi chi, ho chieu
trung cua » truong cua, trung cap, dung cua
cong tan » cong tac, cong san, cong ty
toan tap » toan ban

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 - thanh ((trung cua) OR (trung tuan)) dung ((cong tan) OR (cong thanh)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu tinh - thanh ((trung cua) or (trung tuan)) dung ((cong tan) OR (cong thanh)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - thanh ((trung cua) or (trung tuan)) dung ((cong tan) OR (cong thanh)) toan tap*.
