What are the characteristics of what chairs

In the "Water Margin" often mentioned that green forest who took the first few chairs, then what is the chair ? What are the characteristics of chairs ?

To talk about the chair, you have to speak from the ancient people's sitting method. Before the Han and Wei people, the ancients sat on the ground and naturally had no chairs. When Emperor Hanling was introduced into the “bed of arms” from the north, his appearance was like a low stool. There was also a rope bed at the same time as the bed. The rope is bipedal and can be folded, as it is now Mazar. This rope bed was later called a bed.

During the Sui Dynasty, because the taboo said "Hu", and this chair was characterized by the crossing of the feet of the wood, and it was open and flattened, it was renamed "to bed." In the Southern Song Dynasty, people would rename the bed. It is said that when the prime minister of the Southern Song Dynasty sat in bed, he always turned backwards, and even under the towel, Jing Yin Wu Yuan took Qin Xi's flattery, and he specially put on a back support in the back of the bed, known as the "teacher's chair."

In the hierarchically feudal society, the chair is not a place for anyone to sit. It is a symbol of status and status. It is because of the special role that the chair has, so "taking the first seat" has become synonymous with the leader.

In the workplace, we often hear who made the first few chairs. Many people think that chair is the meaning of the post, but the chair is actually a kind of furniture. Whoever made the first few chairs like the ones just mentioned was derived from furniture. So what exactly is it? Let's look at it with Omido Xiaobian.

Chairs, due to its cross-chair chair foot cross-shaped, hence the name. According to historical research, Maza, which originated in ancient times, can be said to be Mazha with backrest.

Chair features

The structure of the chair is that the legs cross each other before and after, and the intersection point serves as a shaft, and the upper beam wears a rope to replace the seat, which can be folded. The seat ring is generally made of three to five joints, and the lower one is formed by the intersection of eight wooden sticks. The joints are jointed and fixed with metal parts. The entire shape, which looks like multiple triangles from the side, is a lively but lively line, but without losing its stability. Due to the characteristics of its two legs crossed, it is known as a chair.

Chairs can be folded and carried and stored conveniently. They are used not only indoors but also when they are out. In the Song, Yuan, Ming and Qing dynasties, the royal aristocrats or the bureaucrats took out the parade and hunting outdoors, so that the owner could sit and rest at any time and place. This is also known as the row chair and the hunting chair. The origin of the.

In ancient times, the chair was a tool of the emperors and aristocrats, and it was a symbol of status. Therefore, it is only nowadays that there is such a statement as the first chair, which means that someone is the most important role. Although the chairs are easy to move, they are not strong and they don't feel well. Therefore, after the Ming and Qing Dynasties, there have been few chairs. The above is the content of what the Xiaobian introduced is the characteristics of the chair and the chair . I hope to help everyone.
