Chen Pingsheng rides his small electric scooter every day to pick up Chen Lu from school.
While on the way, he also hums a little tune or something.
Chen Lu curiously asks him, "Dad, why do you like singing on the road now?"
"Why? Your dad has lived to this age, can't he enjoy himself a little?"
"It's not that, I just feel a bit awkward, especially when those classmates' parents see us."
"What's wrong with that? You're just too thin-skinned."
Chen Pingsheng drops him off at the school gate, and on the way, he greets a few familiar parents.
When he returns to the neighborhood, he wanders to the market with nothing to do, checking if there's anything he wants to eat that he can buy.
The reason Chen Pingsheng chose to retire early is, first, to focus on teaching his youngest son Chen Lu.
Secondly, the main reason is that he doesn't understand technology.
Now that he's older, he's bound to make errors in future technology predictions.
