Perhaps you should try some spelling variations:
van thanh » ban thanh, van tuan
cua tre » cua te, cuu tre, cua triet
va hanh » van hanh, va thanh, va danh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
hai cua » thai cua, dai cua, hoi cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
ve cac » vien cac

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) xuc ((va hanh) or (van thanh)) hai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) xuc ((va hanh) OR (van thanh)) hai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky lang xa hoi. hieu ((ve cac) OR (va cac)) xuc ((va hanh) or (van thanh)) hai cua tre*".
