He is not a bad person. When he was a fool, people said he was a black sheep. In fact, he is very filial and innocent, just because he is a fool, so he is overbearing. When Fang is smart, he is very scheming and bad, but he is handsome. He made everyone like him at first, in order not to let fools come out to replace him, until everyone began to trust and like him. But he was later infected by the fool and found that the fool was very good, so he completely got rid of the previous evil thoughts and used the same body as the fool, and finally got better.
