I want to find a friend. She doesn't need a mobile phone or qq. Her home phone in Nanjing has not been answered for a year. She should go to school in Nantong. How can I find her?

Have you ever heard of an intranet? See if she's inside. I found that many students in primary schools, junior high schools, senior high schools and universities are like this. You should register one of your own on the campus network first, and then search it. It is common to use your real name on the campus network, so you have a better chance to find her. Of course, you'd better use your real name, otherwise she won't know who you are and will not necessarily add you as a friend! Hehe, I hope you can find your friends.
