The economy of my hometown has improved, but the environment has deteriorated.
Bai Fu, who has become a reporter, went home for vacation this time. The biggest change he saw in his hometown was that the sky was clear, but the haze in the air did not dissipate for a long time.
The old man who used to go out at five o'clock to exercise in the morning light was no longer willing to come out. While Bai Fu was observing all these changes, he saw a wild dog.
The wild dog came towards her like a monster. Bai Fu took out his self-defense tools and tried to drive the wild dog away. At this time, an aunt complained and said to the man next to her, "Why don't you keep the little boy on a leash?"
