Why do men wear earrings on their left ear in Mongolian traditional customs? thank you

Mongolian men wear big earrings and small earrings on their left ear.

Earrings appeared very early in China, and the custom of "looking at ears" was popular in ancient times. The Book of the Later Han Dynasty, Volume 86, Biography of Southwest Yi, pointed out that "people who mourn prison wear noses and ears, and their heads are king, and their ears are three inches under their shoulders, but not over their shoulders." The book Record of Foreign Bodies further explains "Bo 'er": "Bo 'er, a southerner, had two cheeks when he was alive, and his skin was connected with his ear, which was divided into several branches, which were like chicken intestines and hung down to his shoulders." The custom of staring at the ear has died out so far. Of course, ear piercing is still very popular. However, the nose ring is only preserved in individual ethnic groups, such as the Barrow ethnic group. Around the Tang Dynasty, nose piercing was still popular among ethnic minorities in southwest China. Fan Chuo's "The Fourth Collection of Yunnan Famous Categories" once recorded: "The nose-piercing barbarians pierced the nasal septum with a gold ring with a diameter ruler and hung it over their heads. If it is a monarch, it will tie its ring with a silk rope and let people hold it. Secondly, two flower head gold nails are put on from both sides of the nose to expose them in the nostrils. " This situation does not exist among ethnic minorities in Yunnan today.

In this way, rings and pendants hung on the heads of ethnic minorities in China are basically earrings, earrings, earrings and ear strings. In addition to a small amount of gold and jade, a large number of materials are silver, copper, tin and other metals and corals, turquoise, bamboo chips, bamboo sticks, flowers, glass, beads, tassels and so on. Most of them wear silver earrings, and most of them are women, but there are also minority men who wear earrings with both ears or one ear. Now the slightly distinctive niche earrings are listed as follows.
