How to distinguish the laughing cup, the holy grail and the stable cup?

The identification methods of laughing cup, holy grail and stable cup are as follows:

1, laughing cup: a bamboo stick consisting of two planes, that is, two front surfaces. This means that the matter of asking for instructions is not clear enough, and the Buddha can't give clear instructions and needs to ask for instructions again.

2. Holy Grail: A bamboo stick consisting of a flat surface and a convex surface, that is, one yin and one yang. This means that the request can be confirmed or granted.

3. Cup stabilizer: a bamboo stick consisting of two convex surfaces or two concave surfaces. This means that the request is not feasible, or the Buddha does not allow it, so you need to ask again.

4. In the process of throwing grains, it usually takes three consecutive Grails to be an accurate result. If the Holy Grail does not appear three times in a row, it needs to be reinterpreted until it appears three times in a row.
