What children's songs do you remember? ^_^

Children's songs bear our beautiful memory. They are very lovely. They are very cute. They are just like childrens. They are easy to remember and hard to forget. Dear chongzi, I am sure it is not difficult for you to guess the names of the follwoing children's songs. Would you please share with us your happiness when singing these songs?

I can tell you one story. When I was in Grade 4 or 5 in a primary school, our teacher picked up some little boys and little girls to dance for the coming Children's Day. I was among them. The music is "Sing and Smile"(歌声与微笑). I remembered we little boys and girls were in pairs. When We stood in rows, I mean boys are in one row, and girls in the other. We were shy to touch each others' hands. I still remembered my partner. She was a teacher's daughter. And she was pretty pretty. A few years ago, I saw her on the street. She had changed little and was still pretty pretty. I remembered our performance was very good. Her mother, a teacher, made up our faces. And we danced and got a big applause. After the performance, I don't want to wash my face because my face was painted. I was so lovely. To tell you one private thing, I started to brush my teeth from the dance on. In rural areas, children paid little attention to their appearances. Remembering these lovely things, I cann't help smiling. O(∩_∩)O~I love my childhood.
