Due to various folk customs, from a certain point of view, folk beliefs are more complicated.
First of all, avalokitesvara is also a Buddhist. As for Taoist spells and so on, they are all Taoist.
Everything depends on yourself, which one are you willing to accept. In fact, folklore is just a ceremony, and there is nothing profound. Therefore, such a belief can't purify your mind and sublimate yourself. If you have the heart, you should study formal Buddhism or other things.
Now that science and technology are developed, it is very easy for modern people to learn Buddhism. As long as they turn on the computer, they can download it at any time. Compared with the ancients, it is really easy to come.
So, if you want to learn, you can go online and search for the videos of Master Lv Hui or Master Haitao.
These two are exorcists, big monks and great virtues.
Or, you can read the enlightenment book of Buddhism yourself first and get to know what real Buddhism looks like. Then I recommend reading the Spirit and Characteristics of Buddhism, which is written in pure white and well.
