I totally understand LZ's feeling.
Just like what you said, I absolutely admire "那一笑便足以化了整个江南的风情", and I don't think "这辈子还有谁可以替代他", but as one of his fans, I would respect his decision, as long as he feels good. He is an adult, he has right to do what he wants and what he likes. Sometimes people need to take challenge in their lives.
