A special tribe called Kayan is known for wearing rings around their neck. Kayan women often say that their purpose for wearing the rings is cultural identity. The rings are rarely removed since they started wearing them around the age of five. The coiling and uncoiling is a long procedure. They are usually only removed to be replaced by a new or longer set of coils. To set the record straight, women do not suffocate if the rings are removed, though the muscles covered by them are weakened. Many women have removed the rings for medical examinations. Contrary to popular belief, the neck is not actually lengthened. Each coil is replaced with longer coils as the weight of the brass pushes the collar bone down and compresses the rib cage.

在清迈有一个少数民族称做Kayan族，当时为了逃难而来到泰国西北边界的媚洪顺，后来不知为何这支民族的妇女认为长颈才能显示出女人的美丽，因此她们从5岁起就在母亲的协助下在颈子上架起了铜圈，到了10岁开始每年再多加一圈直到25岁为止，到了25岁这些铜圈更可高达25圈重达5至10公斤；铜容易生绿锈，要时常擦拭，而且铜很沉，会将肩膀压塌，所谓的长颈并不是因为颈子变长，而是因为钢圈的重量长期压住锁骨和肋骨，使得脖子看起来变长了。

The pressure of the horse's abdomen had already achieved the acme, Professor Qi, who is rich of experience; saw the problem is at the back of caecum, according to the medicine theory, the caecum full of air is unless great colon or microcolon, if it was great colon, the air should at the right pelvis, it was different between microcolon.
