Use a dollar coin to calculate divination.

If the national emblem (flower) is facing up, draw a circle on the paper; If it really faces up, draw a cross on the paper.

In this way, it is a six-pointed star until it is thrown six times in a row, or a circle or fork is drawn six times from right to left. Corresponding to the following sixty-four hexagrams, you can find your own "good or bad".

Throw one yuan (coin) into the air at will, and see whether the national emblem (flower) is up or literally down after landing.
