My parents worked in 麻花电台, too. That was before I was born.

Then we moved to 新302 宿舍 (behind 广播大厦),  也是广播局宿舍, because my father worked in 广研所 (南礼士路). So when I went to kindergarten, I took 大班车 (石碑胡同<--> 新302) once a week. I am a little younger , so I didn't get chance go to 少年宫, 文革就开始了.  
Does this kindergarten still exist? I really want to go back to visit there next time when I go back to Beijing. It was really nice to talk to you!
