Perhaps you should try some spelling variations:
trinh mach » tinh mach, trinh lich, trinh minh
chu trach » chiu trach, chu thich, chu tich
manh tuan » manh toan, minh tuan, van tuan
theo chu » theo chieu, cho chu, chao chu
anh danh » anh anh, anh dang, anh dinh
dan cong » dang cong, van cong, dan dong
ca dan » cac dan, ca dao

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 trach - ((trinh mach) OR (anh danh)) ca dan cong ((anh tuan) OR (manh tuan)) cau~.
• Adding a wildcard symbol may retrieve word variants: theo chu trach - ((trinh mach) or (anh danh)) ca dan cong ((anh tuan) or (manh tuan)) cau*.
