Perhaps you should try some spelling variations:
su sach » so sach
vu sach » vu bach, vu khach
so sanh » do sanh
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
va dau » va dao
dau vi » dau ve, dau va, dat vi
vi cua » vai cua, di cua
x hoi » xa hoi, o hoi, x ho

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) OR (vu sach))) OR (so sanh)) ky nang x hoi. lieu va cam xuc va dau vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((((su sach) or (vu sach))) or (so sanh)) ky nang x hoi. lieu va cam xuc va dau vi cua tre*.
