Perhaps you should try some spelling variations:
qua cham » qua hai, qua cac, qua cua
va thanh » gia thanh, ban thanh, va tinh
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
va cham » va chat, va tham
va hanh » van hanh, va danh, ban hanh
tai cua » thai cua, tai cuc, tri cua
cua tre » cua te, cuu tre, cua triet
te bac » ten bac, te bao, te ban
bac ky » cac ky, ban ky, sac ky

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: te bac ky lang xa hoi. hieu ((qua cham) OR (va cham)) duc ((va hanh) OR (va thanh)) tai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te bac ky lang xa hoi. hieu ((qua cham) or (va cham)) duc ((va hanh) OR (va thanh)) tai cua tre~".
• Adding a wildcard symbol may retrieve word variants: te bac ky lang xa hoi. hieu ((qua cham) or (va cham)) duc ((va hanh) OR (va thanh)) tai cua tre*.
