Perhaps you should try some spelling variations:
cham xuc » cam xuc, chat xuc, pham duc
van hanh » van thanh, ban hanh, van anh
vu sach » vu bach, su sach, vu khach
nang xa » nang x, lang xa, nang ma
hieu va » lieu va, hieu qua
cua tre » cua te, cua triet, dua tren
cuu tre » cau tren, cau treo
y nang » ky nang, ly nang, v nang

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