Perhaps you should try some spelling variations:
phong lai » chong lai, phong cai, phong la
van phong » van dong, hai phong
su sach » so sach, vu sach
ve cham » va cham, ve chat, vu cham
lai cua » dai cua, hai cua, lai chau
xuc van » duc van, luc van, vuc van
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
ve cam » ve cac, va cam, ve cai
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: su sach y nang ((o hoi) OR (co hoc)). hieu ((ve cam) OR (ve cham)) xuc van phong lai cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach y nang ((o hoi) or (co hoc)). hieu ((ve cam) or (ve cham)) xuc van phong lai cua tre*.
