It means: There is not only one way to govern a country. As long as it is beneficial to the country, it does not have to be rigidly adhere to ancient laws and old systems.

From "Historical Records·Biographies of Shang Jun". In this biography, it mainly describes the historical facts of Shang Yang's reform and innovation in Qin, his merits and demerits, and his reputation in Qin. It also focuses on the critical attitude of Tai Shigong towards his harshness and kindness.

However, Shang Yang’s reform is a successful example in the history of our country. When Duke Xiao was in power, he had entered the Warring States period when the seven heroes were competing for hegemony. The Zhou Dynasty was in decline, and the princes were attacking each other. The struggle was extremely fierce. Whoever wanted to be invincible had to find a way to strengthen himself. Shang Yang followed the trend of history. He met Duke Xiao three times and said that he would use the art of strengthening the country to make Duke Xiao "sit at the banquet without knowing that he was in front of me, and talk for days without getting tired of it." The tacit understanding between the emperor and his ministers laid the foundation for the success of the reform.
