Perhaps you should try some spelling variations:
thai cua » than cua, tai cuc, tri cua
van hanh » van thanh, ban hanh, van anh
cua tre » cua te, cuu tre, cua triet
va hanh » va thanh, va danh, ban hanh
hieu va » lieu va, hieu qua
lang xa » lang ha, dang xay, lang van
ky lang » ky nang, ky dang, ky tang
te sach » toc sach
va cam » va cham, va cac, va cao
te sac » te cac, te san

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 sac) OR (te sach)) ky lang xa hoi. hieu va cam xuc ((va hanh) OR (van hanh)) thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sac) or (te sach)) ky lang xa hoi. hieu va cam xuc ((va hanh) OR (van hanh)) thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((te sac) or (te sach)) ky lang xa hoi. hieu va cam xuc ((va hanh) OR (van hanh)) thai cua tre*.
