He performed a 45-degree tilt in the MV, and used some rope props, just like hanging Weiya now, which can help you keep your balance. After post-processing, the trace of rope in MV can be eliminated, which shows the effect of violating common sense.
But in the stage performance, you can't use this method, it is easy to be seen and there will be no surprise effect of the performance. So they need to use other facilities when there are no other performances, so they made special shoes and stage props to accomplish this. There are some fixable devices on the heel. By connecting with the fixed facilities on the stage, people's heels can be fixed on the stage, making people lean forward.
But when performing on the stage, it takes time to find a fixed position and connect quickly, so when they are looking for a position, they will distract people's attention through some performance forms such as light and shadow effects. Actors can do other operations under the cover of these, and of course, they can directly adjust their positions and design their own scenes to make their behavior look reasonable. These facilities need someone to operate in the background, and the scenes can be smoothly connected to show better results.
Some people think that these facilities use electromagnetic devices, but Michael Jackson applied for a patent for this technology in 1993. At that time, the application of electromagnetic equipment was not as extensive as it is now, and it was not as convenient to control as mechanical facilities, so it was impossible. But now it can be done completely. The maturity of technology has brought new changes, and ordinary people can try it.
Dance lovers should never pursue this without facilities when practicing again. In the process of leaning forward, the change of center makes your heel naturally leave the ground. Normal people can't keep balance in this state, and it can't be achieved by training. And in the process of practice, we must pay attention to the fact that this process puts a lot of pressure on the ankle joint, which is easy to cause joint damage, and if it is not well controlled, your face may be directly patted on the ground, which still hurts, and there may be other physical injuries.
