On the day I was transformed into a poor scholar, I was pinned down in a ruined temple by my creditors and beaten severely.
Suddenly I remembered that I am a Ph. D. In the Department of Physics of Peking University.
The next day, the county government posted a notice: Whoever can solve the problem of urgent delay of 800 miles in the post station will be rewarded with a hundred taels of silver. I built a simple telegraph machine in public, and the county magistrate was shocked.
Half a month later, the enemy's iron cavalry approached the city, and the civil and military forces of the Manchu Dynasty were helpless. I took out the newly ground convex lens and lit the enemy's grain and grass on the city wall. The emperor summoned me overnight and asked me tremblingly who I was studying under.
I pointed to the starry sky: "Your Majesty, my teacher's name is Newton."
