Perhaps you should try some spelling variations:
nang xa » nang x, lang xa, nang ma
hieu vu » hieu va, hieu ve, hieu su
vu cham » va cham, vu kham, tu cham
soc van » hoc van, oc van, sac van
cuu tre » cua tre, cau tren, cau treo
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
anh ve » hanh ve, anh va, thanh ve

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang xa hoi. hieu vu cham soc van ((anh ve) OR (anh viet)) cuu tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang xa hoi. hieu vu cham soc van ((anh ve) OR (anh viet)) cuu tre*.
