There was patriotism even back then. There is a famous story about a merchant, after meeting the enemy army when traveling to another country to sell his cattle, gave all the cattle to the general claiming it was sent by the lord of the state. The general decided to retreat because he thought the intelligence about the invasion was leaked. This event was recorded in Chinese history, and is still used to teach the kids.
