I took a look at the Chinese portion of the discussions and found this post by @Channing in April this year.
It seems he is fine. But another company he started working for was in AI, and various government departments have him busy chugging away, my guess is for research on the COVID-19 pandemic.
You can click the link for the post in Chinese as well as links to various places linked in the post. I will post a Google Translate below, but add my own remarks to what are most likely mistranslations by Google in brackets .
Thank you for your concern. At the moment, I’m fine, I haven’t hung up, but I don’t have enough time to invest in Listary 
I joined an AI startup [company or research group is my guess] in the beginning of last year, mainly for the development and product implementation of some machine learning algorithms. After the outbreak of the new crown epidemic [most likely a literal translation of COVID-19] in January, the company launched intensive cooperation with various government departments, using machine learning and big data [Big Data: What it is and why it matters | SAS] to assist the government in tracing, deduction, and precise prevention and control. I was specifically responsible for the research and development of some of these projects, so the time was very tight a while ago, the forum mailbox did not have time to read, I am sorry to let everyone miss [Re-translation: I did not have time to read the forum mailbox, and I am sorry to miss everyone’s mail/let them sit]. The wave of updates promised years ago was also delayed by the recent situation. Now there are some new ideas about Listary, which is very delicate. The current time is still very tight, and [I] will try to take some time to achieve it.
