The first to walk up were various celebrities. This red carpet photoshoot was a little different from the typical film festival or gala red carpet; the guests didn't need to dress extravagantly, just something slightly more casual.
Also, there was no need to invite big names. Most of the guests were just friends of the directors and actors.
However, since both the director and the lead actors were top-tier domestic stars, the attendees were all fairly well-known celebrities.
