Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
doi chieu » doc hieu, doi chi, ho chieu
tuong cua » truong cua, huong cua, thong cua
cong cong » cong dong, trong cong, dung cong
tung cua » trung cua, dung cua, tang cua
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than ban » thanh ban, toan ban, than man

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: doi chieu sang - thanh ((tung cua) OR (tuong cua)) cong cong dan than ban~.
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - thanh ((tung cua) or (tuong cua)) cong cong dan than ban*.
