Recently, a popular phrase has been circulating online: don't always say "we," "you are you," "I am I." Without common interests, there are no common enemies. Anyone who hasn't hurt me yet is not my enemy. If you insist on creating an enemy for me, then you are my enemy. But in reality, many people have no shared interests with others, yet believe that they and the other party have a common enemy. Humanity's thousands of years of disasters are due to the inability to clarify where their interests lie and to understand who shares common interests with them. One of the purposes of all education is to help people clarify where their true interests are. I believe that sharing common values should lead to shared interests.
