I don't know where the current trend of ten-year retrospectives originated. Maybe QQ. Because I seem to remember that on Singles' Day, the QQ login page said something about "Tencent's tenth anniversary." At that time, I also thought that Pony Ma was really good at timing.
I just went to Baidu and searched for "my ten-year reflections". Sure enough, this activity seems to have been initiated by Tencent. When I first saw this title on someone's blog the other day, I immediately thought of Zang Tianshuo who was recently imprisoned. He has an album called "My Ten Years". It sounds much more straightforward than "My Ten-Year Reflections."
