It was still in culture revolution at my childhood, Mao was still in charge in the 1970s. No commercial radio, tv nor other music pieces could be found in most stores, except revolutionary operas sponsored by mao's wife, as a major part of entertainment, plus once a while army battle movies that people would see in open squares.
Somehow my father got a radio, one day I turned it on and happened to find out the sweet voices and songs from stations in Taiwan, it was so unusual to hear a voice from a lady sounded so tender, warm, and soothing to your heart, later on I found out that the singing lady was Deng Li Jun , the most famous Chinese singing star in 1970s and 1980s, during the period mainland China would normally call Taiwan authority as enemy, so actually I listened to enemy radio station. I covered myself well, as I thought, mostly hiding under a bed or a blanket.
The song the radio played every hour was called " I want to sing for you." (我要为你歌唱）
Here are several lines of lyrics :
I want to sing for you , singing your sorrow and joy, wish I could bring you hope, and take you to a place far away......
