Perhaps you should try some spelling variations:
ban hanh » ban hang
chat xuc » chat huu, cam xuc, chao xu
te sach » toc sach
va hanh » van hanh, va thanh, va danh
hieu ve » hieu va, hieu van
ve chat » va chat, van chat
tang ma » mang may, tang van
nang ma » sang ma, nang cao, mang may
cua tre » cua te, cuu tre, cua triet
di cua » dai cua, doi cua, de cua

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: te sach y ((nang ma) OR (tang ma)) hoi. hieu ve chat xuc ((va hanh) OR (ban hanh)) di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y ((nang ma) OR (tang ma)) hoi. hieu ve chat xuc ((va hanh) or (ban hanh)) di cua tre~".
• Adding a wildcard symbol may retrieve word variants: te sach y ((nang ma) OR (tang ma)) hoi. hieu ve chat xuc ((va hanh) or (ban hanh)) di cua tre*.
