Perhaps you should try some spelling variations:
trung va » truong va, trang va, trung ha
hanh dai » hanh tai, hanh dao, vanh dai
sanh ty » sach ty, canh tay
ty nang » ky nang, ty xang, ty hang
nang xa » nang x, lang xa, nang ma
cua tre » cua te, cuu tre, cua triet
va cam » va cham, va cac, va cao
tuc va » thuc va, truc va, tuc xa

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: do sanh ty nang xa hoi. lieu va cam ((tuc va) OR (trung va)) hanh dai cua tre~.
• Adding a wildcard symbol may retrieve word variants: do sanh ty nang xa hoi. lieu va cam ((tuc va) or (trung va)) hanh dai cua tre*.
