Does not exist. Originated from the movie "Legendary Hometown". There is a clip in this play in which a little girl is born with thick pores and can even put a mung bean in it. The girl's mother has been looking for a way to shrink pores, but she has never found it. Later, the girl's mother heard that this problem can be solved by sesame bathing. The girl's mother bought a lot of sesame seeds to go home, and then let the girl take a bath with sesame seeds. The girl's mother went out of the bathroom because she had other things to do. When she came back, she found that the girl's body was covered with sesame seeds, which were deeply embedded in the girl's pores, while the little girl sat on the ground and kept picking sesame seeds from herself with toothpicks.
