Perhaps you should try some spelling variations:
nhung tuong » nhung huong, nhung phuong, hung vuong
thanh trung » thanh tung
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
theo chu » theo chieu, cho chu, chao chu
chu sach » cau sach, thu sach, chieu sach
dan than » ban than, van than, dan toan
dan chan » dan gian, dan ca, van chat

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: theo chu sach - thanh trung cua nhung tuong ((dan than) OR (dan chan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chu sach - thanh trung cua nhung tuong ((dan than) or (dan chan)) cau*.
