Hello, we can merge this, but please note a few things:

• We view PDFs as authoritative. The metadata on your papers doesn't match, and should be corrected for each of them to "Toby Jia-Jun Li"
• If you want a different canonical name for your author page, that is still a matter of editing fie file you are editing, but you will have to update it to anticipate these corrections
• Please update your name in Open Review / Softconf so that metadata will be correct moving forward. Actually, it may be correct; for a while, aclpub2 was dropping middle names, which is maybe what happened to you.
