Mencius during the Warring States Period had some very good words: "Wealth and honor cannot be corrupted, poverty and lowliness cannot be moved, and power cannot be bent. This is called a true man." This means that high-ranking officials and generous salaries cannot be bribed, and poverty and hardship cannot be bought. He cannot be tortured or threatened with violence. This is what is called a true man. These kinds of behaviors of a man show heroic spirit, which we call having backbone today. Our country has gone through a long period of slave society and feudal society. In every era, there are many such people with backbone. We are the descendants of these people with backbone. We are a nation with a fine revolutionary tradition. Of course, different societies and different classes have different specific meanings of backbone. This must be understood clearly. However, in terms of the principle of unswervingly serving the progressive cause of the time, many of the touching and touching deeds of our ancestors, as well as their positive educational significance, are worthy of our learning. At the end of the Southern Song Dynasty, the capital Lin'an was invaded by the Yuan army. Prime Minister Wen Tianxiang organized armed forces to resist resolutely. After failure and being captured, the Yuan Dynasty persuaded him to surrender. He wrote a poem, including two lines: "No one has died in life since ancient times, leaving behind "Taking loyalty to history" means that people will always die, it depends on how they die, whether they die in humiliation or for the interests of the nation? He chose the latter, wanting to record this piece of loyalty in history. Wen Tianxiang was imprisoned in a dank dungeon in Beijing and tortured. The Yuan Dynasty sent people many times to persuade him that as long as he surrendered, he could become a high official, but he resolutely refused and was finally killed in 1283 AD. Several words spoken by Mencius were reflected in Wen Tianxiang. He wrote the famous "Song of Righteousness", which praised the heroic spirit of ancient people with backbone and sacrificed their own lives to resist oppression, calling on the people to continue to resist. Another story is that there was a poor man in ancient times who was about to die from hunger. Someone threw a bowl of rice to him and said: "Hey, come and eat!" (Hey, come and eat!) The hungry man refused the charity of "come" and If you don’t eat this bowl of rice, you will starve to death later. The story of "eat the food that comes without eating" is very famous and has been passed down for thousands of years, and it also has a positive meaning. The man put on the face of a philanthropist and shouted, "Hey, come and eat!" The taste was unpleasant. After eating this bowl of rice, what about the next step? Obviously, he will not give charity in vain. If you eat his food, you have to do things for him. That poor man has a backbone: looking at your face and demeanor, he would rather starve to death than eat your food. Refusing to eat food that comes to you shows the integrity of the Chinese people. Here's another example. Democracy fighter Wen Yiduo was shot dead by the Kuomintang on July 15, 1946. Before that, his friends got the news that they were going to assassinate him and advised him to hide temporarily. He didn't care and continued to work as usual and worked harder. Knowing that the enemy wanted to kill him, he still shouted loudly a few minutes before he was killed, denounced the Kuomintang agents, and pointed out that their lives would not last long and that people's democracy would surely win. Chairman Mao pointed out in the article "Farewell, Leighton Stuart": "Many people who were once liberals or democratic individualists stood up in front of the U.S. imperialists and their lackeys, the Kuomintang reactionaries. Wen Yiduo took the case and Angry at the Kuomintang's pistol, he would rather fall than surrender." He highly praised him for showing the heroic spirit of our nation.
