A lot. First of all, with the popularity of the Internet, it is not a bad thing for primary school students to get in touch with the Internet early.

Therefore, primary school students should have good self-control when surfing the Internet and consciously resist bad information. There are also temperaments. Bill Gates' daughter has been playing computer since she was sensible, but there is a time limit every day.
