"How will I greet you after all these years?"
At first it was middle school students and middle school students
Then there are vocational high schools and general high schools
Later, firefighters and college students
Finally, the firefighters and teachers
The last one is the fireman and the old lady in the alley
The story must be told from scratch
"We are all ordinary people. But you are my privilege."
Purpose: Only by enduring hardship can one become an ordinary person.
