Brothers can hurt each other and pinch each other in front of you. Then you can curse back and forth. They swore even harder, but they were very much looking forward to what he would curse next. When you are depressed, he will hack you to death and then tell you something darker. If you are drunk and fall beside him, he will laugh at your gaffes in every way and then get drunk as a dog. Maybe you will make an oath, and then no matter how long, you won't say a word, but in fact you have deeply remembered it. Brothers are willing to sleep with you, wear a pair of pants with you, be beaten with you, and accompany you when you are disheartened. Even if you make a big mistake, your brothers will try their best to help you settle it. Life is hard to find a bosom friend, and it is hard to find a bosom friend through the ages. We are brothers in this life and brothers in the next life.
