If you don't get angry, you will treat others as fools, right? If others don't offend me, I won't offend them. If others offend me, I will cut off the roots!

If you are angry, just let it out. If you fart, just let it out. Don't hold it in. You will feel happy, but others will be angry. It's none of my business, and it's none of your business. Mind your own business!
