Perhaps you should try some spelling variations:
hanh vai » hanh vi, hanh va, hanh tai
vai cua » dai cua, hai cua, lai cua
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
san ly » ban ly
ve cac » va cac, vien cac
van ly » van ky, van le, van lu
va cau » van cau, va cac, va dau
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: thuat ((san ly) OR (van ly)) nang x hoi. hieu ((va cau) OR (ve cac)) duc va hanh vai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat ((san ly) OR (van ly)) nang x hoi. hieu ((va cau) or (ve cac)) duc va hanh vai cua tre~".
• Adding a wildcard symbol may retrieve word variants: thuat ((san ly) OR (van ly)) nang x hoi. hieu ((va cau) or (ve cac)) duc va hanh vai cua tre*.
