The details are as follows:

Qian Xuesen: He became a world-famous aerodynamist at the age of 28. When China was liberated, Americans were afraid that he would return to China. At first, they promised high officials and generous salaries, but he was unmoved. Later, he broke through various obstacles and finally returned to China.

Zhu Ziqing: At that time, Zhu Ziqing was suffering from lung disease. At that time, prices soared again, but he still refused to eat food from the United States. Zhu Ziqing is the dean of Tsinghua University, and his monthly income can't support the whole family. Because he had no money to treat the disease, his stomach trouble recurred. In the face of American aid for cheap flour, Zhu Ziqing resolutely refused. In the end, he died because he had no money to treat the disease.

Wen Tianxiang: After being captured by the Yuan soldiers, the Yuan Dynasty tried every means to persuade, force and induce Wen Tianxiang to surrender. The number of people involved in the surrender, the poison of intimidation and inducement, the generous conditions promised and the long waiting time exceeded those of other Steven Song. He would rather die than accept the surrender of Yuan soldiers and was eventually killed.

Source: Mencius and his disciples

Mencius said, "Living in a wide place in the world, standing in the right position in the world, doing the world's great things. Success, with the people; If you are frustrated, you will go your own way. Wealth can't be lewd, poverty can't be moved, and power can't be bent. This is called a gentleman. "

vernacular interpretation:

Mencius said: "a gentleman should live in the widest house in the world-benevolence, stand in the most correct position in the world-courtesy, and follow the most correct road in the world-righteousness. When you can realize your ambition, follow the right path with the people; When you can't realize your ambition, you walk your own path alone. Wealth can't confuse his thoughts, poverty can't shake his integrity, and power can't bend his will. Such a person can be called a gentleman. "

Analysis:

Although Mencius' famous saying about "a gentleman" is inappropriate in criticizing strategists, the famous saying "wealth can't be lewd, power can't be bent" still shines brightly, which has encouraged many people with lofty ideals and benevolence in history and has become their motto of not being afraid of violence and upholding justice.
