Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
thuc day » thuc dan, thuc vat
thuc va » thuc vat, thuc dan
vai cuu » vai cua
te sach » toc sach
ly nang » ky nang, ly hang, ly vang
cuu tre » cua tre, cau tren, cau treo
y nang » ky nang, v nang, may nang
va cao » va cac, va co, va dao

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