Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
vai cua » dai cua, hai cua, lai cua
van anh » tuan anh, van minh
tu san » thu san, tu ban, tu can
san ky » sang ky, van ky, dan ky
va cai » va cac, va bai, va dai
ve cac » va cac, vien cac

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 san ky nang xa hoi. hieu ((va cai) OR (ve cac)) xuc ((van anh) OR (van thanh)) vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu san ky nang xa hoi. hieu ((va cai) or (ve cac)) xuc ((van anh) OR (van thanh)) vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu san ky nang xa hoi. hieu ((va cai) or (ve cac)) xuc ((van anh) OR (van thanh)) vai cua tre*.
