Why does the chair fly? What are his shortcomings?
According to historical records, the recliner is a magical flying machine. It is said that it can fly more than a foot above the ground. However, in fact, this statement is probably just an exaggerated description, which is not necessarily true.

As for the flight principle of the chair, it is said that "there are organs under it and the teeth are staggered." When people sit in a chair, they kick the board with their feet and turn around and gallop away. " This is obviously a human-driven flight mode, which requires human power to hit the machine on the board to rotate the chair, thus generating wind rotation, and then making the chair fly off the ground. This way of flying is obviously very dangerous, because once out of balance or lack of strength, the chair may not fly normally and even cause an accident.

In addition, even if the chair can really fly, its practicability is questionable. First of all, the chair itself is a tool for sitting and lying, not for flying. Secondly, as a means of transportation, the speed and load of chairs are not as good as other means of transportation. Thirdly, the chair needs manpower to fly, which also limits its scope and occasions.

To sum up, the chair can't really fly. Even if it can fly, it has many shortcomings and limitations. Therefore, we should treat these legends and stories rationally and don't trust their authenticity.
