Perhaps you should try some spelling variations:
hieu van » hieu va, thien van, lieu va
hanh tai » thanh tai, hang tai, han tai
hieu ve » hieu va
va hanh » van hanh, va thanh, va danh
tai cua » thai cua, tai cuc, tri cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
cua cu » cua chu, cua cau, cua su
x hoi » xa hoi, x ho, 5 hoi
o hoi » co hoi, o hoc, o hai

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 sac ky nang ((x hoi) OR (o hoi)). ((hieu ve) OR (hieu van)) phan tu va hanh tai cua cu~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((x hoi) or (o hoi)). ((hieu ve) or (hieu van)) phan tu va hanh tai cua cu*.
