Perhaps you should try some spelling variations:
ban hanh » ban hang
lang van » dang van, tang van, hoang van
tu sach » thu sach, su sach, te sach
vai cuu » vai cua
cac xuc » cam xuc, cac nuoc, chat xuc
sach ty » sach y, sach tu, sach thu
hieu ve » hieu va, hieu van
lang xa » lang ha, dang xay
cuu tre » cua tre, cau tren, cau treo
ve cac » va cac, vien cac
va dan » ca dan, va dao, va dau

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: tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve cac xuc ((va dan) OR (ban hanh)) vai cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve cac xuc ((va dan) or (ban hanh)) vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ty ((lang xa) OR (lang van)) hoi. hieu ve cac xuc ((va dan) or (ban hanh)) vai cuu tre*.
