Perhaps you should try some spelling variations:
qua cham » qua hai, qua cac, va cham
cham xuc » cam xuc, chat xuc, cham soc
so sanh » do sanh
xuc van » duc van, luc van, vuc van
hanh di » hanh vi, hanh de, danh di
hang di » hang doi, hang vi, hang dien
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu cac) OR (so sanh)) ky nang x hoi. hieu qua cham xuc van ((hanh di) OR (hang di)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu cac) or (so sanh)) ky nang x hoi. hieu qua cham xuc van ((hanh di) OR (hang di)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu cac) or (so sanh)) ky nang x hoi. hieu qua cham xuc van ((hanh di) OR (hang di)) cua tre*.
