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
phan cau » phan dau, phan tu, phan lap
phan cac » nhan cach, phan dau, phan lap
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 ((phan cau) OR (phan cac))~.
• 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 ((phan cau) OR (phan cac))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu tinh) or (chiet tach)) - thanh tung ho dung cong ty ((phan cau) OR (phan cac))*.
