Know yourself, know the enemy, and know each other. This kind of person "few" has a close friend to understand himself. I believe you have heard the story of high mountains and flowing water, high mountains and flowing water.
The mountains are green and the water is green. The mountains and flowing water are looking for a close friend. A sound, like a cry, like a complaint, like a cry of sorrow. Sadly, it is rare to find a confidant in life, and a bosom friend is the most difficult to find throughout the ages... A bosom friend is hard to find in the mountains and rivers. Poems and articles, and how to do it. Let me drink wine with you, and I will get drunk every month. Happy or sad, contented.
I don’t need to tell you what I mean. You probably understand that it’s hard to find a close friend, but if you find one, you’ll cherish it
