"Common agreement" is formed by one's own blood and soul, and is forged in the Hengnan sacred tree. It is another "self" in the world. When you live, he lives; when you die, he also dies. Even if everyone in the world will betray you, your "community" will not, trust you, and respect you. With you as the sky and you as the earth, that is the "common understanding" that belongs only to you.
