Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, cham soc
van hanh » van thanh, ban hanh, van anh
su sach » so sach, vu sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
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 ty nang xa hoi. hieu qua ((cham xuc) OR (chao xu)) van hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: su sach ty nang xa hoi. hieu qua ((cham xuc) or (chao xu)) van hanh vi cua tre*.
