In this chapter, we learn that the main protagonist of the day is the stone for gambling. Mr. Tang suggests that the rest of the event be dedicated to stone gambling. He explains that stone gambling is a form of gambling in which one cut can bring a person poverty or wealth. At this point in time, no machine can see the inside of a stone, so no one can determine whether or not there is jade inside. The stones on the table are called "covered goods" because they don't show any signs of being cut into. The value of the stones depends on luck. Everyone knows that the stones at the table come from the mine where Sun's jewelry is stored. The owner of the jewelry shop, Master Sun, is invited to inspect the goods. Master Sun is a veteran in the field of jade mining. He's the owner of a jewelry shop. He was invited to look at the goods because he's an expert in this field. The smell of jade in the jade tunnels makes Master Sun want to buy the stones immediately.
