Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
thuc day » thuc dan, thuc vat
hanh hai » thanh hai, nhanh hai, hang hai
tu sach » thu sach, su sach, te sach
sach ty » sach y, sach tu, sach thu
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
van dau » van dao, phan dau
truc va » thuc va, thuc vat, trung va
hai cua » thai cua, dai cua, hoi cua
cua tre » cua te, cuu tre, cua triet

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: tu sach ty nang xa hoi. hieu van dau ((truc va) OR (thuc day)) hanh hai cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ty nang xa hoi. hieu van dau ((truc va) or (thuc day)) hanh hai cua tre*.
