Yes but what research institute are they affiliated with? For all I know this is an pseudonymous TikTok user who is good at faking videos. Why should I take this for anything but complete fiction?
Certainly not making any claims of the legitimacy, just providing the original sources. There doesn't seem to be any attribution besides the anonymous account.
The Chinese subtitles in the first demonstration claim "further efforts will be made to reduce impurities", then the subsequent video claims "technical details will be published once they are properly organized and documented".
