The higher the soul level, the more one lives like a child.

It's not that they haven't grown up, but that after seeing the world clearly, they still choose to stay pure.
They can blend into the crowd, and also enjoy solitude peacefully;
Having seen the complexity of human nature, they cherish simplicity even more;
They understand that one must be cautious of others, but still are willing to believe in the power of sincerity.
