Perhaps you should try some spelling variations:
thanh khung » thanh hung, thanh chuong, thanh phuong
chieu tinh » trieu tinh, lieu tinh, chau tinh
doi chieu » doc hieu, doi chi, mot chieu
khung cua » chung cua, khung luan, chung cu
tong cong » trong cong, dung cong, dang cong
cong cong » cong dong, trong cong, dung cong
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 tinh - thanh khung cua ((tong cong) OR (cong cong)) dan than ban~.
• Adding a wildcard symbol may retrieve word variants: doi chieu tinh - thanh khung cua ((tong cong) or (cong cong)) dan than ban*.
