Perhaps you should try some spelling variations:
thanh tung » thanh cong
hoc thieu » toc thieu, hoc hien
ho chieu » theo chieu, doi chieu, mot chieu
tung dai » trung dai, tuong dai, tung dan
dai cong » dai cuong, tai cong, doi cong
cong tan » cong san, cong thanh, cong ty
cong tac » cong ty
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) OR (hoc thieu)) sach - thanh tung dai cong ((cong tan) OR (cong tac)) phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sach - thanh tung dai cong ((cong tan) OR (cong tac)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (hoc thieu)) sach - thanh tung dai cong ((cong tan) OR (cong tac)) phan cau*.
