Perhaps you should try some spelling variations:
thanh tuong » thanh thuong, thanh huong, thanh cuong
chieu xanh » chieu sach, chieu sang, chieu tinh
thanh tung » thanh cong
doi chieu » doc hieu, doi chi, ho chieu
dong cong » duong cong, dung cong, dang cong
cua dong » chua dong, cua cong, cua dang
tan than » tan thanh, ban than, tam than

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 xanh - ((thanh tuong) OR (thanh tung)) cua dong cong ((tan than) OR (tan tran)) cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu xanh - ((thanh tuong) OR (thanh tung)) cua dong cong ((tan than) or (tan tran)) cap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((thanh tuong) OR (thanh tung)) cua dong cong ((tan than) or (tan tran)) cap*.
