Perhaps you should try some spelling variations:
hieu ve » hieu va, hieu van
luc ban » cuc ban, luc bat, luc van
duc ban » duc tan, duc van, dua ban
hanh ve » hanh vi, hanh va, hanh kem
cuu tre » cua tre, cau tren, cau treo
sai ky » sac ky
ve cam » ve cham, ve cac, va cam
ve cuu » ve cau, ve chu, ve cua
x hoi » xa hoi, o hoi, x ho

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: te ((cac ky) OR (sai ky)) nang x hoi. hieu ve cam ((luc ban) OR (duc ban)) hanh ve cuu tre~.
• Adding a wildcard symbol may retrieve word variants: te ((cac ky) or (sai ky)) nang x hoi. hieu ve cam ((luc ban) or (duc ban)) hanh ve cuu tre*.
