Perhaps you should try some spelling variations:
thanh trung » thanh tung
nhung cong » dung cong, thong cong, hang cong
trung cua » truong cua, trung tuan, trung cap
cua nhung » va nhung
ho chieu » theo chieu, hoc thieu, doi chieu
ban than » ban thanh, van thanh, ban hang
van than » van thanh, van thang, van tuan
doi chi » doi khi

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) OR (doi chi)) sach - thanh trung cua nhung cong ((ban than) OR (van than)) cau~.
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (doi chi)) sach - thanh trung cua nhung cong ((ban than) or (van than)) cau*.
