A system launched by China's Ministry of Public Security (MPS) to track down missing children has seen a 98.2 percent success rate, while more technology will be applied in efforts to combat human trafficking. 

The TuanYuan system, or "Reunion" system in English, was launched on May 15, 2016, posting information on all missing children along with their photos, names and time and location of disappearance. The information is also sent to apps to notify users nearby.  

By early June, the system had posted information on 3,978 missing children with 3,901 of them found, a success rate of 98 percent, according to the Xinhua News Agency. 

The longer a case continues, the more police officers and people will receive notifications, and the notification range will also be expanded. Some new media platforms are also used.

On Sina Weibo, the system posts information on all lost children cases, and updates are given on cases when the children are found. 

Xiao Yueying, 13, was reported missing in a community in Beijing at around 4 pm on May 5. She was later found at the airport in Kunming, Southwest China's Yunnan Province at 3 pm on May 27. 

Zhang Zhiran, a 2-year-old boy, went missing at around 6 pm in Baoshan, Southwest China's Yunnan Province. He was found and identified by his parents on the same day. Local police confirmed the boy died by drowning, the system posted. 

The Reunion system will apply more technology, such as facial recognition, in order to crack cases that occurred years ago. "If a child was abducted years ago, the shape of his face might be different, AI can process facial recognition across ages based on photos," Chen Shiqu, deputy director of the criminal investigation bureau under the MPS, told the China Daily on June 4.
