Kneeling is a form of sitting in Japan. It's from Chinese studies.

In the traditional culture of China, kneeling is a way to strengthen the kneecap. Unlike many people now, you can't do it without your old knees.

Kneeling, only bending down again, shows respect for each other. If you touch the ground further, it is generally the highest form of respect for each other. Of course, in the big gift, there are so-called three kneels and nine knocks, which is the respect (etiquette) for the son of heaven.

However, with the introduction of chairs, high furniture has gradually become popular, and people in China are also accustomed to lying high. At this time, the etiquette of kneeling on the ground gradually became inferior. Kneel only when expressing obedience or worship.

However, Japan and South Korea still use this kneeling position in many traditional occasions.

That's why there is the difference between China, Japan and South Korea. In fact, the essence of this sitting method is to show respect for each other.
