When he challenged the demon gate, his head went in, but his body got stuck in the middle. First of all, this behavior is really dangerous, and there is no need to deliberately challenge this action. In addition, it shows that children's shoulders and lower limbs are much wider than their heads. First of all, his body proportion has been seriously deformed. If his head can't get out, he can go through the door with his whole body, so he can go out.
Because if the head can pass, if the body proportion is just right, the body will certainly pass. This shows that his figure is not as perfect as expected and has a deformed orientation. In addition, it may be the angle. Just when you can't throw it in, the posture and angle are right. When you want to quit, you panic. The posture and angle are wrong, and your head gets stuck in the middle.
Also, if you can't throw it in, the position of the ear also has a lot to do, because after all, the angle between the skull and the ear is not very easy to adjust, so it is normal that the head can't retreat. As a little boy, we don't need such a challenge. After all, being in good shape is not really good, but being in good health and good physical quality is really healthy. We should recognize this reality and not make such unnecessary challenges.
