Perhaps you should try some spelling variations:
ban banh » ban hanh, ban danh, ban thanh
cham xuc » cam xuc, chat xuc, cham soc
cua tre » cua te, cuu tre, cua triet
ban anh » ban hanh, ban danh, bang anh
va cham » va chat, va tham
hieu va » lieu va, hieu qua
sac ky » cac ky
nang o » nang co, nang ho, nang ro
de cua » le cua, te cua, dieu cua
o hoi » co hoi, o hoc, o hai

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 ((sac ky) OR (sai ky)) nang o hoi. hieu va cham xuc ((ban anh) OR (ban banh)) de cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sac ky) or (sai ky)) nang o hoi. hieu va cham xuc ((ban anh) OR (ban banh)) de cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu ((sac ky) or (sai ky)) nang o hoi. hieu va cham xuc ((ban anh) OR (ban banh)) de cua tre*.
