What do people near Bayannaoer City in central Inner Mongolia mean by "portal"? I don't know if it's these two words, but it's the pronunciation anyway.

I'm from Bameng, Inner Mongolia, and the portal mentioned by Bameng means "body odor". Under normal circumstances, before getting married, both parents will find someone to ask if there is a "portal" in the other party. If there is, it is often disapproved, because body odor is a genetic disease that will be passed on to the next generation, thus making this family "smelly" from now on. I heard that some women's parents will personally smell men's clothes to make sure they are reliable. There are many body odor diseases in southerners, which actually belong to the problem of sweat gland development, and it is indeed hereditary!
