I'm a novice tarot card, and I don't know much about tarot cards. I want to ask.

Whether to open the light or not is superstition. You must believe that tarot cards are scientific. It really doesn't matter whether it's bright or not. I bought two import cards, neither of which lit up or anything. I took them apart and used them for two years, and the accuracy has always been high. So, no problem, opening up is actually just a psychological comfort, if you really want to open a lot of tutorials online. The key to improving the skill of playing cards lies in practice. Anyway, this is my experience in these three years. On the basis of certain practice, and with the guidance of corresponding good books, your card skills will advance by leaps and bounds. Since you are a novice, don't worry too much. Look at the basics first, what is the meaning of the card, and then calculate it for others. You must think more about them, and then you will know a lot. Then read advanced books. Novices are advised to read the Tarot Sunflower Collection, which is enough. Read 78-degree wisdom and tarot inversion when advanced. I don't know after that. I am also a person with only three years of divination experience, and I am also exploring the road of advanced development.
