Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sang » chieu xanh, hieu lang, nhieu tang
chieu sach » chinh sach, chiet tach, chieu xanh
trung dai » truong dai, truong dao, trung tam
dai duong » dai cuong, hai duong, dai luong
thanh lap » thanh san, phan lap, thanh hai
cong dan » cong tan, huong dan, cong dong
cong san » cong tac

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 sang) OR (chieu sach)) - thanh trung dai duong ((cong dan) OR (cong san)) thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (chieu sach)) - thanh trung dai duong ((cong dan) OR (cong san)) thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sang) or (chieu sach)) - thanh trung dai duong ((cong dan) OR (cong san)) thanh lap*.
