"Party" is the most commonly used conceptual system for Shanghainese to classify social phenomena. So there is a name called "scalper party", which is used to describe a bunch of people snapping up materials or tickets there, just like the phenomenon of "scalper". "Yellow Cattle" is the characteristic of Shanghai Beach with a history of two centuries. The former "scalper party" was engaged in the intermediary behavior of excessive differentiation. As far as the phenomenon is concerned, it is defined as "relying on strength or power to buy materials and tickets, and then selling them at a high price for profit". Before liberation, they poured gold, while during the Cultural Revolution, they poured sewing machines, bicycles, televisions and other tickets. In the new century, the "scalper" industry has made greater development, and began to sell tickets for the Grand Theatre and the hotline train until the world's first maglev ticket. The existence of "scalpers" directly led to the "difficulty in buying tickets" in Spring Festival travel rush.
