After the Spring Festival, the silence of the Ten-Li-He market for more than half a month became bustling again. Here is a relatively concentrated construction material and home furnishing market in Beijing, and also an area with a relatively concentrated population of migrants. Unlike the enthusiastic business atmosphere inside the market, a special group of people are also busy. However, they do not dare to hawk loudly, but whisper to the passers-by: "Cash out?" The "cash out" they mentioned refers to cashing out credit cards.
