Perhaps you should try some spelling variations:
chieu tinh » trieu tinh, lieu tinh, chau tinh
chiet tach » chieu sach
thanh tung » thanh cong
dung cong » dung trong
than cau » toan cau, phan cau, thanh chau
than cap » khan cap, thanh lap, thanh cac
tung ho » tuong ho, trung hoc, trung hoa
ho dung » hoc dung, hoi dung, so dung

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) OR (chiet tach)) - thanh tung ho dung cong ty ((than cau) OR (than cap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu tinh) or (chiet tach)) - thanh tung ho dung cong ty ((than cau) OR (than cap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chiet tach)) - thanh tung ho dung cong ty ((than cau) OR (than cap))*.
