I want to ask a foreigner you don't know, knowing your birthday, is it effective to cast a spell on you in the distance? That man should be a master of Feng Shui.
It is useful to have your date of birth, name, address and photos, otherwise there are so many people with the same eight characters that it is useless to you. Besides, people who will cast spells on you must be evil, and such people will be punished sooner or later. Don't worry, landlord. There are very few such people. Don't be afraid even if you meet them unfortunately. Because of the causal cycle, he will take the consequences. You just need to be yourself.
