cua tre » cua te, cua triet, dua tren
cac xuc » cam xuc, cac nuoc, chat xuc
hieu ve » hieu va
bai ky » ban ky, sai ky, bac ky
tu bai » tu ban, tu bat, te bai
x hoi » xa hoi, o hoi, x ho

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: tu bai ky nang x hoi. ((hieu ve) or (hieu van)) cac xuc van hanh dinh ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu bai ky nang x hoi. ((hieu ve) OR (hieu van)) cac xuc van hanh dinh ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu bai ky nang x hoi. ((hieu ve) or (hieu van)) cac xuc van hanh dinh ((cua tre) OR (cuu tre))*".
