hanh vai » hanh vi, hanh va, hanh tai
cay phoi » cap phoi, tay hoi, cay cho
cua tre » cua te, cuu tre, cua triet

cac luc » cau luc, coc luc, cac nuoc
hieu va » hieu qua

luc va » duc va, tuc va, loc va
tu san » thu san, tu ban, tu can
tu sac » tu sach, tu cac, tu bac

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) OR (tu san)) ly va cay phoi. ((hieu va) OR (lieu va)) cac luc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu san)) ly va cay phoi. ((hieu va) or (lieu va)) cac luc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu san)) ly va cay phoi. ((hieu va) or (lieu va)) cac luc va hanh vai cua tre*.
