What is the principle of fortune telling with chopsticks?

Is it accurate to give birth to boys and girls with chopsticks?

Not allowed. But chopsticks can move. I have tried, and I feel that there is a magical power to make chopsticks move. Of course I'm an atheist! Fortunately, I am good at physics. In fact, it can be explained by physical stress analysis At first, two people should aim at the chopsticks and form a line. There is almost no force to push forward, just gently let the chopsticks touch each other. When the ends of chopsticks touch and the two chopsticks are roughly in a straight line, in order to keep this state, two people need to push the chopsticks forward, so that the two chopsticks can exert force and prevent separation. Because the two chopsticks are approximately straight at first, the chopsticks will not be deformed. But after a long time, people's hands become unstable, and the force of pushing chopsticks out unconsciously becomes greater, and the balance of chopsticks in a straight line is broken, and two chopsticks will bend from the place where they touch. I don't know who Daxian is, but she has something to do with having boys and girls.
