Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
ho chieu » theo chieu, hoc thieu, doi chieu
tung cua » trung cua, tuong cua, dung cua
cua tong » cua cong, cua dong, cua nong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
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 - thanh tung cua tong ((cong tan) OR (cong tac)) ((than cau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh tung cua tong ((cong tan) or (cong tac)) ((than cau) OR (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh tung cua tong ((cong tan) or (cong tac)) ((than cau) OR (phan cau))*.
