Is it useful to tell a fortune when a person is missing?

It can be counted as six hexagrams, commonly known as divination, and it is possible to predict the whereabouts of this person. Of course, if you have calculated it many times, it is not allowed.

This is a technique based on China's traditional learning "Zhouyi". People who study it deeply can be very beneficial to its divination problems. Of course, there are too many people who fool a little knowledge now, and some people use it to cheat money even if they can master the mystery, thus ruining a science.
