Perhaps you should try some spelling variations:
khong cong » thong cong, khong cang, chong cong
hua khong » hoa khong, cua khong, hoac khong
san thanh » ban thanh, van thanh, son thanh
ho trieu » mot trieu, 30 trieu, ho chieu
25 trieu » 30 trieu
anh tang » anh bang, anh dang, anh nang
tang hua » tang ha, tang cua, tang luan
san than » sang than, ban than, van than

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 trieu) OR (25 trieu)) tinh - anh tang hua khong cong ((san than) OR (san thanh)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho trieu) OR (25 trieu)) tinh - anh tang hua khong cong ((san than) or (san thanh)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho trieu) OR (25 trieu)) tinh - anh tang hua khong cong ((san than) or (san thanh)) cau*.
