In China, there are over 200,000 children disappearing every year. Many parents use their own efforts to look for their children. Unfortunately, only 0.1% of the missing children can be found. The most critical issue is that the missing children's information are not widely accessible to people. China has 600 million mobile-phone users today. No matter where they are, people have the habit of searching for Wi-Fi connections. We use the mobile platform to rapidly extend the influence. People search for free Wi-Fi and help search for missing children. 600 million mobile phone users help us search for missing children.

Equipped with a special signal transmitting system, we developed our proprietary Wi-Fi hot-spots system to provide connection. When people turn on their WLAN, they can search for WI-FI hot-spots named after SOS messages from missing children. If they want to connect to this Wi-Fi network for free, they should share missing children's photos and information on social media, such as WeChat Moments, Sina Weibo. Different wi-fi names with different information would be shown to people on a random basis. Through our satellite Wi-Fi hot-spots, we let the 600 million mobile phone users reach our media to help search for missing children.
