Perhaps you should try some spelling variations:
thuc van » thuc vat, thuc dan, thuc hanh
te sach » toc sach
nang xa » nang x, lang xa, nang ma
thuc va » thuc vat, thuc dan, thuc day
cua tre » cuu tre, cua triet, dua tren
y nang » ky nang, ly nang, v nang
va cam » va cham, va cac, va cao
cua te » cua tu

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 sach y nang xa hoi. lieu va cam ((thuc van) OR (thuc va)) hanh vi ((cua tre) OR (cua te))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang xa hoi. lieu va cam ((thuc van) OR (thuc va)) hanh vi ((cua tre) or (cua te))~".
• Adding a wildcard symbol may retrieve word variants: te sach y nang xa hoi. lieu va cam ((thuc van) OR (thuc va)) hanh vi ((cua tre) or (cua te))*.
