I have seen the video.
The coat is blocking the gate, and I really don't know how to get in.
I'll decrypt Renren.com, Lisangao County, Qingdao.
This is similar to the magic of wearing glasses displayed at the Spring Festival Gala. First, people in the circle close to the magician need an assistant to ensure that they completely block the line of sight, and the mother of the child needs to collude first (the child depends on the situation and can be controlled by the mother ...).
As for technology,
The first possible technology came to mind after watching the video of the masked magician, that is, the seemingly integrated railing is actually segmented, with built-in springs, and both ends of the railing are connected with the springs respectively, which can be separated and automatically restored (suddenly thinking of the arm exerciser for exercise ...), and can enter between two such railings from bottom to top in turn when crossing; But it is unreasonable that this situation requires the whole body to pass through the same two poles. If this technology is really used, Liu Qian should have enough flexibility to lift his legs high. He also needs prosthetic props and his mother's coat.
