The famous couplet written by Li Dazhao: "Iron shoulders carry moral principles, and skillful hands write articles!" It was originally written by Yang Jisheng, a cultural celebrity in the Ming Dynasty. Li Dazhao only changed one word in the original couplet. Yang Jisheng, a famous cultural figure in the Ming Dynasty, was brutally murdered by Yan Song because he resisted rape and opposed the powerful traitor Yan Song. Before his execution, Yang Jisheng wrote a famous couplet: "Iron shoulders bear moral responsibility, and hard hands are responsible for articles."

1916 September One day in August, a friend of Li Dazhao asked him to inscribe a couplet. He remembered this couplet, so he wrote ten characters "Iron shoulder to bear moral responsibility, skillful hand to write articles", and encouraged him to communicate with his friends.

It's just that Li Dazhao cleverly changed the word "spicy" to the word "miao". The difference between the word "spicy" and "miao" shows Li Dazhao's cautiousness and rigorous writing. . Unknown to later generations, they thought this couplet was written by Li Dazhao, and the misunderstanding persists to this day. From this word, we can also see Li Dazhao's own ambition and pursuit.

The "morality" in the first line refers to the ideals and aspirations of serving the country and the people. "Carrying morality and justice" means taking saving the country and the people as one's own responsibility; the "article" in the second line refers to promoting Marxism-Leninism and criticizing Reactionary warlord rule, works praising revolution and communism. "Writing articles with clever hands" means writing more and better articles to promote the revolution.
