How to get a custom title in Tianlong Babu Gang (can the deputy leader change it? )

The deputy gang can't change its custom title. Only Wang can change it. You can press ALT+O to open the gang. There is a custom title, and you can see the title changed by the gang leader. If your job title is changed and you want that job title, you can find 50 tributes to get a hot stamping sticker and go to the Prime Minister of Luoyang to change it.
