19 16, Li Dazhao founded the morning bell in Beijing and designed to write a warning every issue. There is an epigram in "Morning Bell No.6", which was rewritten by Li Dazhao from Yang Jisheng's "Holding Morality with Iron Shoulder and Writing with Skillful Hands". Yang Jisheng, whose real name was Jiao Shan, was born in Jiajing period of Ming Dynasty, and was a famous loyal minister in Ming Dynasty. It is a true portrayal of his principles of life. In the struggle against the great traitor Yan Song, Yang Jisheng did not fear power and wrote a letter of "ten crimes and five traitors" to Yan Song. Later, Yang Jisheng was put into prison by Yan Song. Although he was tortured and indomitable, he was eventually victimized by Yan Song. At that time, at the request of his wife Wu Ruonan, Li Dazhao changed the word "spicy" to "wonderful" in the couplet, and presented Zhang Yi with a couplet, which was often quoted. In the early years of the Republic of China, Shao Piaoping, a famous journalist, quoted Yang Jisheng Lianzhong in 19 18. 1945, Zhou Enlai also presented Liu Yazi with the calligraphy of "iron shoulders bear morality, iron hands write articles". It is right to express our determination to uphold justice and pursue truth.
