We always see the glamorous side of the stars on the screen. When we especially like an idol star, we especially want to have an intersection with each other in reality. Stars are usually very busy at work, and they can only see themselves when they attend activities. I believe that every time ordinary people see a star, they want to take a group photo or sign it. Therefore, the stars' every move is in people's attention. It is normal to be chased at the event site, and there are crazy fans who specialize in guarding the star's door or following the star's car, regardless of their own safety.
Just like when Lu Han took part in an activity, the activity was over and other fans had already left, but some fans still hired scalpers' cars, followed Lu Han's cars and even ignored traffic laws, hoping to be closer to their idols. This is simply idolizing with their lives.
Stars always give people a mysterious feeling, so every time they appear privately, they will be photographed by the masses. However, this is also a process that a public figure must go through. Since we live in the spotlight, we must expose our every move and accept public criticism and supervision by public opinion.
