The so-called "different ways of governing the world" means that the law of governing the world is not rigid. "The country is illegal since ancient times" means that the country is suitable and does not imitate people. Governing the country cannot be done in one way, but should be changed according to the actual situation. Legalists advocate that the old method should be changed, instead of sticking to it when it has failed.
Shang Yang (about 395 BC-338 BC) was a statesman, reformer, thinker and representative of Legalism in the Warring States Period. He is a native of Wei (now Liangzhuang Town, Neihuang County, Anyang City, Henan Province) and a descendant of the king of Wei. Her surname is Gong, so she is also called Wei Yang and Gong Sunyang. Later, due to his meritorious service in the Hexi Campaign, he was awarded the title of fifteen cities, Shang Jun, so he was called Shang Yang.
