Perhaps you should try some spelling variations:
thanh hai » thanh phan, thanh hoa, thanh san
ban thanh » ban hanh, ban hang
cua tre » cua te, cuu tre, cua triet
hai cua » thai cua, dai cua, hoi cua
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
duc ban » duc tan, duc van, dua ban
va cam » va cham, va cac, va cao
su sac » su sach, su cac
su xac » pu xac, su cac
va cai » va cac, va bai, va dai

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: ((su sac) OR (su xac)) ky lang xa hoi. hieu ((va cai) OR (va cam)) duc ban thanh hai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) OR (su xac)) ky lang xa hoi. hieu ((va cai) or (va cam)) duc ban thanh hai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su sac) OR (su xac)) ky lang xa hoi. hieu ((va cai) or (va cam)) duc ban thanh hai cua tre*.
