I think you are gilding the lily by doing so. You should remember the telephone number according to the psychology and habits of the public. For example, your number is 8888 80 10 or five 80 10, according to everyone's habits. You should respect the public's own psychology and don't try to impose your ideas on them. This figure is very good. Some people will remember this number like this, with 8 in front and area code behind it. However, if the things you modify are too complicated, at least you will get the impression that the simpler you want to remember, the more you can remember, so you don't need to think so much. You just need to highlight your original number 888880 10 and let everyone remember it according to their own habits. I believe no one can understand "telephone number: 88888- Beijing area code/+Beijing area code" at a glance. Therefore, it is better to use the original telephone number and let the public write it down according to their own habits. Everyone has been dealing with phone numbers since childhood, and you can't change everyone's habits, so the best way is to use your phone number as it is.
