After 70 days offline, I think I am now in a better mental and emotional state, find myself desperately missing you all, and am ready to get back online.
I have registered for a new XMPP account and created a new SimpleX profile, and the contact information is available on my main page. As for Matrix, my request for a pub.solar ID has been sent but is still pending, so please be patient; I will update the information on my main page as soon as possible.
And there is one very important thing I would like to clarify: so that instant messaging is truly instant, both my XMPP account and my Matrix account are now managed at the Express level, and I will no longer separate them into Private and Express. This means I will use one XMPP account and one Matrix account whether I am indoors or outdoors. If your threat model is particularly severe, you should use SimpleX; if you want a middle ground, use XMPP, as I will still keep the OMEMO fingerprints separate between the Private group and the Express group, and you can treat Express fingerprints as untrusted.
Over the next few days, I will try to contact you all. Please keep an eye on your messaging apps.
