The earliest saying of body odor should be "Hu odor", which, as the name implies, is the body odor of Hu people, mainly referring to the Hu merchants from the western regions in ancient times, belonging to Caucasian race, and can also be said to be the body odor of ordinary white people. Because there was no distinction between whites and blacks in ancient Asia, China called them "conference semifinals" in ancient times. Because the sweat glands of the body have not been purified and subsided, it is easy to produce body odor, which is very similar to the fishy smell of foxes, so it can also be called body odor. Maybe it's because I think beards are discriminatory, especially many descendants of Hu people who have lived in China for a long time. In order to avoid discrimination, I changed my name to body odor. In China, body odor is regarded as a disease, which is really hard to smell. Most East Asians don't have body odor. If so, maybe their ancestors have the lineage of the conference semifinals. Most white people have it, if not, it may be mixed with East Asian blood. In western countries, it is easy to buy deodorant in supermarkets, just to deal with body odor, but in China, this product is hardly seen, which also reflects the actual situation of human body odor in the west from one side. If you keep a good habit, take a bath every day and cover it with perfume, all whites and blacks can, but. If you sweat for two days and don't take a bath, it's a long story. In China, some people who have this body odor are actively treated, but unfortunately, this feature is hereditary, so in ancient China, marrying a Han nationality made people with body odor disgusted.
