Scalper Party is commonly known as scalper in Beijing, whose jargon is patchwork, and Shanghainese call it scalper Party. In recent years, Shanghai dialect is also called "piling mildew", and there is a more vivid metaphor to call this kind of people "ticket bugs".
The scalper party originated from the food stamps issued by the government in the 20th century, and some people sold them. At that time, it was not called ox, but ox. Later, they sold train tickets. Its origin may lie in describing a group of people snapping up materials or tickets like scalpers, and it is collectively called scalpers.
