Perhaps you should try some spelling variations:
chiet tach » chieu sach
nhung cong » dung cong, thong cong, hang cong
truong va » truong dai, truong cao, truong dao
thanh lap » thanh san, phan lap, thanh hai
ho chiet » ho chieu, ho thiet, hoc thiet
trung va » trang va, trung ha, trung tam
cong dan » cong san, cong tan, huong dan
than cau » toan cau, phan cau, than cap

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 chiet tach - thanh ((trung va) OR (truong va)) nhung cong dan ((than cau) OR (thanh lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chiet tach - thanh ((trung va) OR (truong va)) nhung cong dan ((than cau) or (thanh lap))~".
• Adding a wildcard symbol may retrieve word variants: ho chiet tach - thanh ((trung va) OR (truong va)) nhung cong dan ((than cau) or (thanh lap))*.
