$Piin is life itself, a natural expression of those who are truly living at the bottom of society. They have no money, no way to get rich, and can only dream together with their poor buddies and sisters. It is completely different from other empty words created to chase the trend. There are no big guys in #Piin. Most of them are ordinary people who can't even afford 10,000 yuan. Of course, this is different from the bottom of society mentioned by other people. They can only buy#Piinby scrambling.
