Zhang Fan spent his days working on construction sites and his nights posting ads for a real estate agent. After twenty days of hard work, he still lacked over two thousand yuan for his tuition fees.,More than four years as a street vendor has allowed Zhang Fan to experience the harshness of society prematurely. Almost every time he speaks, there is a careful smile on his face, a sad pre-emptive laugh!,That's how he won two or three hundred yuan for the day. He didn't dare to win more. After all, it was just a small gambling den. If he smashed it and cleaned everyone out, no one would be stupid enough to play with Zhang Fan anymore. Who wants to play if someone is always winning without losing。
