Perhaps you should try some spelling variations:
ban hanh » ban hang
tu sach » thu sach, su sach, te sach
vai cuu » vai cua
cac xuc » cam xuc, cac nuoc, chat xuc
cuu tre » cua tre, cau tren, cau treo
hieu ve » hieu va, hieu van
y lang » _ lang, tay lang, yen lang
va dan » ca dan, va dao, va dau
o lang » hoa lang, hoi lang
ve cac » va cac, vien cac

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 ((y lang) OR (o lang)) xa 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 ((y lang) OR (o lang)) xa hoi. hieu ve cac xuc ((va dan) or (ban hanh)) vai cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) OR (o lang)) xa hoi. hieu ve cac xuc ((va dan) or (ban hanh)) vai cuu tre*.
