Perhaps you should try some spelling variations:
chap thuong » chan thuong, phan thuong, pham thuong
thuong cong » thong cong, thuong con, thuong dong
manh tung » manh hung, thanh tung
tung chap » dung chat, tung pham, dung chau
dan than » dan chan, van than, dan toan
ban than » ban thanh, van thanh, ban hang
ho lieu » co lieu, ho kieu, ho chieu
so lieu » so dieu

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 lieu) OR (so lieu)) tinh - manh tung chap thuong cong ((dan than) OR (ban than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho lieu) OR (so lieu)) tinh - manh tung chap thuong cong ((dan than) or (ban than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho lieu) OR (so lieu)) tinh - manh tung chap thuong cong ((dan than) or (ban than)) cau*.
