"Liang Shang Jun Zi" is a famous quote from the ancient Chinese novel "Water Margins". The original text was "Liang Shang Jun Zi acts chivalrously to protect the people so that everyone can live and work in peace and contentment." The meaning of this sentence was that the gentleman on the beam (the Liangshan hero) protected the people so that everyone could live and work in peace and contentment. In the novel, the Liangshan heroes chose to rebel against the imperial court because they were dissatisfied with the corruption of the imperial court and the oppression of the ruling class. They put righteousness first, and in order to protect themselves and the people they cared about, they did not hesitate to take risks or even sacrifice their lives. Their actions received widespread support and eventually succeeded in establishing a relatively peaceful society, setting an example for future generations. The meaning of this sentence emphasized the importance of chivalrous spirit, that is, people should uphold justice and morality, bravely protect their own interests and rights, and at the same time provide help and support to the vulnerable groups in order to achieve social harmony and stability.
