Perhaps you should try some spelling variations:
hang hang » nang hang, cang thang, hung thang
ho trieu » mot trieu, 25 trieu, 30 trieu
hanh san » thanh san, khach san, thanh son
va thong » va thuong, va phuong, va cong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than tap » toan tap, han tap, phan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "ho trieu tinh - ((hang hang) OR (hanh san)) ((va thong) OR (he thong)) cong dan than tap~".
• Adding a wildcard symbol may retrieve word variants: ho trieu tinh - ((hang hang) OR (hanh san)) ((va thong) OR (he thong)) cong dan than tap*.
