Brother-in-law hasn't contacted his family for eight years. How can he find it? Thank you.

Several methods: 1, report to the public security bureau, post on the Internet, and look for you; 3, find a love association that specializes in finding people; 4, find a smart fortune teller to work out the general orientation for you; 5, collect relevant information about your brother-in-law when doing the above things, such as date of birth, photos, characteristics, personality and previous simple experiences.
