Perhaps you should try some spelling variations:
cham xuc » chat xuc, cham soc, pham duc
tu sach » thu sach, su sach, te sach
va vanh » va van, va hanh, va anh
tai cua » thai cua, tai cuc, tri cua
va danh » va dinh, va dan, va hanh
cua tre » cua te, cuu tre, cua triet
sach ky » sac ky, sach y, sach ty
nang o » nang co, nang ho, nang ro
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 sach ky nang o hoi. lieu va ((cham xuc) OR (cam xuc)) ((va vanh) OR (va danh)) tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang o hoi. lieu va ((cham xuc) OR (cam xuc)) ((va vanh) or (va danh)) tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ky nang o hoi. lieu va ((cham xuc) OR (cam xuc)) ((va vanh) or (va danh)) tai cua tre*.
