Perhaps you should try some spelling variations:
thanh moi » thanh loi, thanh hoa, thanh hai
nang xa » nang x, lang xa, nang ma
hieu va » hieu qua
luc ban » cuc ban, luc bat, luc van
duc ban » duc tan, duc van, dua ban
moi cua » hoi cua, doi cua, moi quan
cua tre » cua te, cuu tre, cua triet
su xac » pu xac, su cac
xac ky » cac ky, sac ky, bac ky

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: su xac ky nang xa hoi. ((hieu va) OR (lieu va)) dau ((luc ban) OR (duc ban)) thanh moi cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky nang xa hoi. ((hieu va) or (lieu va)) dau ((luc ban) OR (duc ban)) thanh moi cua tre~".
• Adding a wildcard symbol may retrieve word variants: su xac ky nang xa hoi. ((hieu va) or (lieu va)) dau ((luc ban) OR (duc ban)) thanh moi cua tre*.
