Example: Lu Xun chewed pepper to drive away the cold

Mr. Lu Xun studied hard since childhood. When he was a teenager, he studied in Jiangnan Naval Academy, and got excellent grades in the first semester. The school awarded him a gold medal. He immediately took it to the streets of Nanjing Drum Tower to sell it, then bought some books and a bunch of red peppers. Whenever it is cold at night and reading at night is unbearable, he picks a pepper and chews it in his mouth, making his forehead sweat. He used this method to drive away the cold and insisted on studying. Because of his hard study, he finally became a famous writer in China.
