Perhaps you should try some spelling variations:
thanh trung » thanh tung
chieu sang » chieu sach, chieu xanh, hieu lang
thanh chau » thanh cha, thanh cham, thanh chu
trung cap » truong cao, trung tam
dong cong » duong cong, dung cong, dang cong
thanh lap » thanh san, phan lap, thanh hai
ho chieu » theo chieu, hoc thieu, doi chieu
cap dong » cao dong, cau dong, ca dong
cong dan » cong san, cong tan, huong dan

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 - thanh trung cap dong cong dan ((thanh chau) OR (thanh lap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - thanh trung cap dong cong dan ((thanh chau) or (thanh lap))*.
