Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh tai » thanh tai, hang tai, han tai
loai san » loai nam, loai va, luan san
van cham » van chat, van tham, va cham
cham xuc » cam xuc, chat xuc, cham soc
tai san » tai ngan
hanh va » hang va, hanh vi
cua tre » cua te, cuu tre, cua triet
xuc va » duc va, tuc va, luc va
x hoi » xa hoi, o hoi, x ho

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 cac ((loai san) OR (tai san)) x hoi. hieu van cham xuc va ((hanh tai) OR (hanh va)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu cac ((loai san) OR (tai san)) x hoi. hieu van cham xuc va ((hanh tai) or (hanh va)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu cac ((loai san) OR (tai san)) x hoi. hieu van cham xuc va ((hanh tai) or (hanh va)) cua tre*.
