This is a proverb which means that unless you teach someone how to do something, they will not learn how to do it. If you don't show a man how to catch fish, he will stay hungry. most people need to be shown how to do something, that way they can practice and remember.

yes it's very nice say. i draw you a hat. it's very impressive. i hope i will see anothers things like today. bye

The meaning is a bit like this proverb: "Show me and I will forget, teach me and I may remember, involve me and I will understand". It has multiple meanings depending on what angle you look at it but I view it as "The easiest option isn't always the best".
