Perhaps you should try some spelling variations:
thanh khung » thanh hung, thanh chuong, thanh phuong
chieu sang » chieu sach, chieu xanh, hieu lang
doi chieu » doc hieu, doi chi, mot chieu
khung cua » chung cua, khung luan, chung cu
tong cong » trong cong, cong cong, dang cong
dung cong » dung trong
danh toan » manh toan, anh toan, dan toan
toan ban » van ban

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - thanh khung cua ((tong cong) OR (dung cong)) danh toan ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - thanh khung cua ((tong cong) OR (dung cong)) danh toan ban*.
