Perhaps you should try some spelling variations:
thanh tuong » thanh thuong, thanh tung, thanh huong
chieu sach » chinh sach, chieu sang, chieu xanh
nhung cong » dung cong, thong cong, nhung don
tuong cua » truong cua, huong cua, thong cua
hang cong » dang cong, hang nong, bang cong
dan phan » doan phan, dan chan, van phan

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 sach) OR (chiet tach)) - thanh tuong cua ((nhung cong) OR (hang cong)) dan phan tu~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chiet tach)) - thanh tuong cua ((nhung cong) or (hang cong)) dan phan tu~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) OR (chiet tach)) - thanh tuong cua ((nhung cong) or (hang cong)) dan phan tu*.
