Perhaps you should try some spelling variations:
hanh trinh » canh tranh, hanh chinh
trinh quan » tinh quang, trinh luat, trinh han
thong cong » trong cong, tong cong, thong thong
nhung don » nhung van, nhung bo
25 trieu » 30 trieu
dan than » dan chan, ban than, dan toan
van than » van thanh, van thang, van tuan

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: 25 trieu tinh - hanh trinh quan ((nhung don) OR (thong cong)) ((dan than) OR (van than)) tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "25 trieu tinh - hanh trinh quan ((nhung don) or (thong cong)) ((dan than) OR (van than)) tap~".
• Adding a wildcard symbol may retrieve word variants: 25 trieu tinh - hanh trinh quan ((nhung don) or (thong cong)) ((dan than) OR (van than)) tap*.
