There seems to be a sentence in a joke. I remember that the sky was still blue and the house was for people to live in. Who knew there was a sky-high reward? ...

At that time, the sky was blue, the water was green, crops were growing in the field, pork was safe to eat, mice were afraid of cats, the court was reasonable, marriage was the first thing to fall in love, barbershops only cared about haircuts, medicine could cure diseases, doctors saved lives, filming did not need to accompany the director to sleep, taking pictures required clothes, and the money owed was paid back. The father of the child was very clear and the school was not interested.
