Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
cam duc » cam xuc, cao duc, pham duc
va danh » va dinh, va dan, va hanh
danh vi » hanh vi, dinh vi, danh di
cua tre » cua te, cuu tre, cua triet
sac ky » cac ky, sai ky
vi cua » vai cua, di cua

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 ((sach y) OR (sac ky)) nang xa hoi. ((hieu ve) OR (hieu van)) cam duc va danh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: tu ((sach y) or (sac ky)) nang xa hoi. ((hieu ve) or (hieu van)) cam duc va danh vi cua tre*.
