Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
vanh dai » van dai, vanh tai, lanh dao
tu sach » thu sach, su sach, te sach
hieu va » lieu va, hieu qua
va cham » va chat, va tham
va vanh » va van, va danh, va hanh
cua tre » cua te, cuu tre, cua triet
y nang » ly nang, v nang, may nang
co hoi » co hoc, co loi
xuc va » duc va, tuc va, luc va
o hoi » o hoc, o hai, o hoa

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 nang) OR (ky nang)) ((o hoi) OR (co hoi)). hieu va cham xuc va vanh dai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (ky nang)) ((o hoi) or (co hoi)). hieu va cham xuc va vanh dai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) OR (ky nang)) ((o hoi) or (co hoi)). hieu va cham xuc va vanh dai cua tre*.
