As a teenager, I seemed to learn about the outside world mainly through a homemade ore radio. When I became a young man, it was my wish to have a portable semiconductor radio. After that, it seemed that before I knew it, I slowly estranged from the radio with so many people, even though I had so many radios, big and small. Also, in the cultural market at present, there are so many newspapers and periodicals, TV channels can not be selected, who still pay attention to capture the sound of the announcer fluttering in the sky? Among the three major media, the newspaper, the television and the radio, Newspapers flourished, television flourished, and broadcasting seemed to be a bit of a "shortage of cars and horses in front of the door." Memories of sitting around a radio in the '60s and' 70s listening to live sports games made life feel like a different world.
