Perhaps you should try some spelling variations:
hanh dong » anh dong, ha dong
dong cua » dung cua, cong cua, huong cua
tu sach » thu sach, su sach, te sach
van cau » van dau, van hau, van chat
va hanh » van hanh, va thanh, va danh
y nang » ky nang, ly nang, v nang
co hoi » co hoc, co loi
xuc va » duc va, tuc va, luc va
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 sach y nang ((x hoi) OR (co hoi)). hieu ((van nam) OR (van cau)) xuc va hanh dong cua vat~.
• Adding a wildcard symbol may retrieve word variants: tu sach y nang ((x hoi) or (co hoi)). hieu ((van nam) or (van cau)) xuc va hanh dong cua vat*.
