The ancients loved divination. The essence of divination is nothing more than looking for random numbers from nature to solve doubts. After all, things always force people to make choices, begging for random numbers arranged by nature or gods, and it is easy to get inner peace. The earliest random number generators discovered by China were tortoise shells and animal bones.

People drill the bone shell first, and then burn it, which produces a random shell, but burning the shell is very troublesome, after all, it is not environmentally friendly. The second important random number generator discovered by China people is Yarrow.
