Zhao Yutao named himself Changsheng because the name was both "ancient" and had a good meaning. He hopes that he can live a long life and be buried together with a man who is as ordinary as himself in a hundred years. He came into this world alone, out of place and terrified. He didn't want to leave this world alone, alone and helpless.
Modern/ordinary Gongshou/Shou is not one-to-one/Shou has two or three relationships, right?
Intention: People always come alone and leave alone.
