Perhaps you should try some spelling variations:
van thanh » van tuan
ban thanh » ban hanh, ban hang
hieu van » hieu va, thien van, lieu va
vu sach » vu bach, su sach, vu khach
sach ky » sac ky, sach y, sach ty
van cam » van nam, van lam, van cau
hai cua » thai cua, dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ky nang x hoi. hieu van cam xuc ((van thanh) OR (ban thanh)) hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sach ky nang x hoi. hieu van cam xuc ((van thanh) OR (ban thanh)) hai cua tre*.
