I had a bike when I was a kid and as long as I was home for dinner, nobody cared. I biked a lot. Like 2 or 3 cities over, maybe 25 miles each way. Parents thought it was good exercise. I now realize that it was freedom. I went to tge computer store and played games on the computers I could not afford. Also, in hindsight, biking was the physical thing that I needed so that I didn't punch someone, or worse. I had lots of rage and took it out on the road. I averaged 18MPH, which is pushing pretty hard.
Part 2: until social media, I never realized how messed up the Chinese culture is. I'm sorry to hear that you are going through all this.
As a kid, me and a friend bought the game "Leisure Suit Larry" or one of the sequels. It included an age check because of adult content. After asking our age, which we dutifully entered as 19, it would ask questions that only an adult would know, like "who was the US president in 1962?" We would research these questions in my friend's encyclopedia to play the game.
Now, I have all this trivia knowledge in my head due to my childhood quest to see highly pixelated cartoon boobies in 640x480 resolution.
