Perhaps you should try some spelling variations:
toc sach » hoc sach, doc sach, thuoc sach
va thanh » gia thanh, ban thanh, va tinh
cham xuc » cam xuc, chat xuc, cham soc
lam cua » nam cua, lam chat
va danh » va dinh, va dan, dia danh
va hanh » van hanh, ban hanh, dao hanh
sach ky » sac ky, sach y, sach ty
vu cham » va cham, vu kham, tu cham
hieu vu » hieu va, hieu ve, hieu su
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet

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: toc sach ky nang xa hoi. hieu vu cham xuc ((((va hanh) OR (va thanh))) OR (va danh)) lam cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky nang xa hoi. hieu vu cham xuc ((((va hanh) OR (va thanh))) or (va danh)) lam cua tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach ky nang xa hoi. hieu vu cham xuc ((((va hanh) OR (va thanh))) or (va danh)) lam cua tre*.
