Thirty Years Ago, I Went Barefoot For The Exam

In the winter 30 years ago, I had been jumping in the countryside for nearly four years. The commune where I cut the queue is more than 50 kilometers away from the county. That year, I signed up for the college entrance examination. The day before the exam, I was worried about how to go to the county seat for the college entrance examination. I heard that there was a tractor going to the county seat the next day.
The next morning, several of our educated youth who participated in the college entrance examination went to the commune with luggage and books. I didn't expect to go late. The carriage was full of people. Fortunately, at that time, we didn't talk about overloading or overloading, so we all squeezed up.
On the road, I found that there was a square thing in the corner of the car, wrapped in a sack. Isn't it an excellent stool! But why is no one sitting? Whatever it is, sit down first. I sit on it.
It took three or four hours for the tractor to arrive at the county seat. It was very cold in December, and my feet were already frozen. When I jumped off the tractor, the educated youth who went with me looked at me and exclaimed: how can you be barefoot!
Looking down, my sole and sock sole are gone, only the uppers and socks are hanging on my feet. At this time, I suddenly realized that I was sitting on an abandoned lead-acid battery. The overflow of waste acid had corroded the soles of my shoes and socks, but fortunately, my foot was not injured. I remember that at that time, I did not know who lent me a pair of rubber shoes, so we rushed to find a place to stay.
Although very embarrassed to participate in the college entrance examination, but this year I was admitted to the University, life has changed.
