hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua

cua tre » cua te, cuu tre, cua triet

tu sac » tu sach, tu cac, tu san
ke va » te va
ky va » my va, ky la, y va

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 sac ((((ky va) OR (ly va))) OR (ke va)) xay hoi. hieu van cac xuc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((((ky va) OR (ly va))) or (ke va)) xay hoi. hieu van cac xuc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: tu sac ((((ky va) OR (ly va))) or (ke va)) xay hoi. hieu van cac xuc va hanh vai cua tre*.
