What does the smile between two people mean when drawing lots?

Laughing cup is a noun in divination. The so-called "cup" is actually a very traditional divination thing like cashew kernel. There are two pieces, one flat and the other convex. When divining, first ask you the question you want to divine, and then throw it on the ground. If a plane faces upwards and a convex face faces upwards, it is the "holy grail", which means beauty. If both planes are facing up, it is a "laughing cup" and that is a "positive cup". Both pieces are convex upward, indicating "stable cup" and "negative cup", indicating that it is not good, and * * * throws it three times.
