One day in September, 19 10, the American cruise ship "empress of china" sounded its horn in Wusong Port. "ah! Isn't this Hu Hongqi (the original name of Hu Shi)? " "Hey, it's Zhu Kezhen! Why aren't you dead? " "Thanks to you! At that time, you said that I would not live to be 20 years old, which made me swim, run and exercise every day. I made up my mind that I must live longer than you. It is hard to say who will die first in the future! " Two years ago, Zhu Kezhen and Hu Shi went to junior high school together in Shanghai Chengzhong School. Zhu Kezhen was short, thin and morbid at that time, so Hu Shi once said that he would not live to be 20 years old. This time, when we met on the cruise ship, Zhu Kezhen had lived for more than 20 years. But Hu Shi refused to admit defeat and said, "Although you have lived for more than 20 years, judging from your appearance, you can't live anyway, let alone live longer than me!" Zhu Kezhen knew he was joking when he heard something unlucky. He knows that Hu Shi is brilliant, outspoken and competitive, but he keeps a low profile and likes to be a good person. However, Zhu Kezhen never refused to accept Hu Shi's short-lived prediction, and firmly believed that his innate emaciation could be made up by training the day after tomorrow. Two years later, they met again and started gambling. Zhu Kezhen asked, "What if I live to be in my sixties?" Hu Shi readily replied: "If you live to be 60 years old, I will kowtow to you three times in front of all my relatives and friends on your 60th birthday. If you live longer than me, you can kick my corpse's ass. " "All right. You must remember what you said today! " Zhu Kezhen said. Zhu Kezhen was born in 1890, one year older than Hu Shi. After betting, he insisted on exercising and developed a good habit of swimming, hiking and practicing boxing regularly. Moreover, he lives a regular life, does not smoke or drink, and gets up early and goes to bed early. Even though I was displaced and lost my wife and children, I never relaxed my physical exercise. His wife recalled: "The first thing in the morning is to record the eyes, rain, wind direction, temperature and air pressure of that day. If it snows, we should also measure the thickness of the snow, and then do gymnastics, play Tai Ji Chuan and exercise. Diet is moderate, no matter whether the food is good or bad, it is never picky and excessive. " Later, Zhu Kezhen lived to 1974, at the age of 84, and died suddenly in Beijing. He kept a diary until the night before his death. Hu Shi only lived to 1962 at the age of 7 1. However, due to two friends, one in Chinese mainland and the other in Taiwan Province, Hu Shi had no chance to kowtow to Zhu Kezhen on his 60th birthday. When Hu Shi died, Zhu Kezhen didn't kick his ass.
