Why don't many roadside fortune tellers use Daoism?

Speaking of "Daoism", everyone knows that it is unfathomable metaphysics.

Most people don't understand or even know where to start. For thousands of years, only great gods such as Jiang Taigong, Zhuge Liang, Liu Bowen and Yuan Tiangang can understand, master and use it.

So, what is Daoism?

In principle, Daoshu is a magic book in ancient China, and it is the first secret among the three treasures of Qimen, Liu Ren and Taiyi. Its essence is an advanced astrophysics. Reveals the role of the eight planets in the solar system and the earth's magnetic field. This alone can be compared with the lost Mayan civilization, the top civilization.

Some scholars believe that it is the highest realm of Taoist divination and a book of divination. We often see "fortune tellers" dressed as Taoist priests on the roadside, posting Taoist signs to attract business.

In the author's view, this kind of metaphysics must be true and it may be reasonable to predict the future. However, most of the "fortune tellers" that can be seen in the world rely on the name of metaphysics, and there are absolutely few real skills and practical learning.
