I remember this song. I was at elementary school in the early to mid 80's. We had a music teacher who liked singing. He could play the accordion and taught us many popular songs from Taiwan. This song was in the official textbook. "Dear uncles and aunts", that was actually from another song, "They are like the bees brewing the sweet life for us." I remember how we loved to sing with him, the lanky young man with the accordion. But retrospectively, I suspect him to be a pedophile. Why would a young man like him work in elementary school, where 99% were female teachers?
The PE teacher was definitely a pedophile, 'cause once I saw him fondling a girl in the equipment room. No one would question his behaviors, though.
