How much should black magic be kept?

Why do you keep dark magic? Of course, it's because he's rough and cheap, and he can change it when he dies. Generally, this kind of fish is used to keep out evil spirits.

In addition, it is the problem of positioning. Every year, the position of Huang Wu changes. Putting eight stones and six black magic stones into the pot water will have the effect of stopping disasters and turning evil spirits into evil spirits, which means 1.6.8 Shan Zhi. When placing the fish tank, remember to pay attention to the position of Huang Wu.
