Perhaps you should try some spelling variations:
su sach » so sach
vu sach » vu bach, vu khach
te sach » toc sach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao
xuc va » duc va, tuc va, luc va
vi cua » vai cua, di cua

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 (te sach)) ky nang xa hoi. hieu va cam xuc va hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((((su sach) or (vu sach))) or (te sach)) ky nang xa hoi. hieu va cam xuc va hanh vi cua tre*.
