寻找走失亲子十四年的父亲何治生，走遍大江南北，最终在山东淄博与摄制组相遇。摄制组跟随拍摄走失儿童父母群体数日，期间父母们用传单，广播，直播等手段扩散孩子们的信息，有人出手帮忙转发，也有人冷眼旁观。 　　He Zhisheng, who had searched for his son for 14 years, traveled all over the country and eventually met a filming team in Zibo, Shandong Province. The team followed a group of parents searching for lost children. The parents spread the info of children by flyers, broadcasts, and livestreams on SNS. Some people helped, while others watched indifferently.
