What are the fortune-telling customs in Zhenjiang?

Why do people give candy after divination?

Baby: Hello, there was such a custom in the old society. When others help with divination, they should give candy to others. At that time, the fortune teller didn't want anything but some candy, and then he exchanged candy for some food. The reason why there are stalls and diviners is to earn some pocket money, feed their families and eat a full meal.
