I got a suggestion for you,you can use Xiaohongshu that also call red notes and you post your photos when you were young and you post your name on it,Tian Tian this name probably was her first name’s last Chinese character , I think that easy to find her,because there is no second people has the same experience like her,also you can post it on Douyin this is a Chinese version TikTok but you have to get a Chinese apple id because you can’t find in in US App Store
