What is the main difference between Legalists and Confucians concerning how the ruler should conduct himself in order to most effectively govern his subjects and protect his kingdom? Do you agree with Confucius or Han Fei? Why?

Note : The second part of your question is opinion based hence it won't be answered. Thank you.

Ancient China had one of the earliest civilizations in the world along with ancient Egypt, Indus and Mesopotamia. The very first written records in Chinese history has been dated to 1600 BC to 1050 BC i.e. under the Shang dynasty. But the first dynasty was the Xia Dynasty which had existed from c. 2070 BCE to c. 1600 BCE. Ancient China is also known to be the nation which first invented gunpowder and paper.
