Will the eight characters tell others to change? I'm so scared ...

Don't worry, what you said about being changed by people will not happen. The name must be combined with the eight characters. Seeing the eight characters requires information such as gender, birthplace and birth time. This is normal.

There are very few people who can use the eight characters to do some special things, which is not good for the numerologist itself. Even doing good things will be bad for the numerologist, let alone doing bad things.

So, you don't have to worry about these problems.
