What does it mean to throw a laughing cup inside and outside the Guanyin spirit?

Cup, also called "Fu", is a tool used by the ancients to pray for good or ill luck to the gods and communicate with them. It is made of two tree roots or bamboo roots into a half-moon shape, which has two sides, the outside is flat, the inside is called Yin, and the outside is called Yang. Both of them are positive, indicating a sneer with unknown good or bad luck, commonly known as "laughing cup"; Both of them are negative "anger cups", meaning the wrath of the gods, commonly known as "Buwu Cup"; One-on-one mistakes are the holy grail, also known as the "oil cup", the "holy grail" and the expression of the gods' promises.

In modern society, lottery fortune-telling has been widely used on the Internet. However, due to the particularity of the Internet, laughing cups frequently appear in online lottery, which leads to inaccurate calculation. After long-term observation, it is found that the laughing rate is low when the network is fast and stable, and the laughing rate is high when the network is slow and stuck. So choose the right time to measure, or choose the winning number and then find a signature to check. But superstition is superstition after all, so we should treat these things rationally.
