Perhaps you should try some spelling variations:
te sach » toc sach
nang xa » nang x, lang xa, nang ma
va hanh » van hanh, va thanh, ban hanh
va danh » va dinh, va dan, dia danh
vai cua » dai cua, hai cua, lai cua
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, ly nang, v nang
va cao » va co, va dao, va bao

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang xa hoi. lieu ((va cao) or (va cac)) thuc ((va hanh) OR (va danh)) vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang xa hoi. lieu ((va cao) OR (va cac)) thuc ((va hanh) OR (va danh)) vai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. lieu ((va cao) or (va cac)) thuc ((va hanh) OR (va danh)) vai cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. lieu ((va cao) or (va cac)) thuc ((va hanh) OR (va danh)) vai cua tre*.
