Perhaps you should try some spelling variations:
mai hoi » mai khoi, dai hoi, lai hoi
qua cac » cua cac
cac soc » cac toc, cac hoc, cham soc
va hanh » van hanh, va thanh, va danh
cua tre » cua te, cuu tre, cua triet
tu sac » tu sach, tu san, tu bac
soc va » hoc va, loc va, doc va
vi cua » vai cua, di cua

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sac) OR (tu cac)) ky nang ((ma hoa) OR (mai hoi)). hieu qua cac soc va hanh vi cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sac) OR (tu cac)) ky nang ((ma hoa) OR (mai hoi)). hieu qua cac soc va hanh vi cua tre*.
