Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
hieu ve » hieu va, hieu van
cam duc » cam xuc, pham duc, nam duoc
cao duc » dao duc, cao suc, giao duc
va hanh » van hanh, va thanh, va danh
vai cua » dai cua, hai cua, lai cua
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky
co hoi » co hoc, co loi
cua te » cua tu
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: tu sac ky nang ((x hoi) OR (co hoi)). hieu ve ((cam duc) OR (cao duc)) va hanh vai cua te~.
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang ((x hoi) or (co hoi)). hieu ve ((cam duc) or (cao duc)) va hanh vai cua te*.
