kham xung » khac xuong, khac tung, khai ung
kham xuc » kham cuoc, cam xuc, chat xuc
te sach » toc sach

ly nang » ky nang, ly hang, ly vang
cua tre » cua te, cuu tre, cua triet
y nang » ky nang, v nang, may nang
ma hoi » mai hoi, xa hoi, ma hoa
va dao » ca dao

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) or (ly nang)) ma hoi. hieu va ((kham xuc) or (kham xung)) va dao dau cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (ly nang)) ma hoi. hieu va ((kham xuc) OR (kham xung)) va dao dau cua tre.
• Adding a wildcard symbol may retrieve word variants: te sach ((y nang) or (ly nang)) ma hoi. hieu va ((kham xuc) or (kham xung)) va dao dau cua tre*.
