If you have anything to say, you can leave me a message with the form to the right. You can also directly email me at

gro.yratemoc[ta]gnehciq

which is equivalent to submitting the form.

I am also on the fediverse at

cometary.org/@qicheng

where I occasionally post about happenings in astronomy or other miscellaneous thoughts. You're welcome to follow or message me on there as well through, e.g., Mastodon, or another compatible ActivityPub instance.
