First, Miss Sister did this to make a nice video.
There is such a video on the Internet. In the Shanghai subway, a young lady is doing a difficult movement. Her hair is tied to the handrail of the subway, her body is suspended, her legs are crossed, and she is playing with her mobile phone in her hand, just like on a swing, which makes people feel scared. She did this just to make a video that she was satisfied with. It turns out that she is a circus performer. She has been doing this training for six months, and it is the first time to do this on the subway. In order to shoot a satisfactory video effect, she constantly adjusts the angle of her mobile phone, which looks dangerous.
Second, she sent the video online, which can get clicks and satisfy her vanity.
I believe everyone knows, right? Head hanging beam? This allusion, the ancients did it in order to study hard and get ahead. But the young lady hung her head to get more hits. Maybe she hopes that she can attract more people's attention and get everyone's praise and comments, so as to gain more fans and help her work. More importantly, satisfy your vanity and feel that you have a certain sense of existence.
Third, little sister's behavior should be condemned.
This young lady is a professional actress, and her daily job is to perform constantly, which won a lot of applause. However, she should not take such a dangerous action to the subway. If you don't ride in a civilized car, you will probably hurt her or others because of negligence or some accidental collision. It may also make some people curiously imitate such actions and affect the riding environment of other passengers. This lady thinks this action is very common, but to most people, it is very strange and dangerous. I hope she can listen to others' opinions with an open mind, realize her mistakes, and take a civilized bus in the future.
