He repeatedly stated that the sample stands up(become straight) when the object is nearing it, and drop down when its far. The same applies for the negative polarity(same behaviour on N/S).

Thanks, that makes sense from context. It sounded to me like the first syllable was rú, which got me wondering whether 铷 rubidium magnets are a thing... I found a patent for a "rubidium iron boron permanent magnet" https://patents.google.com/patent/CN102832038A/en but I guess that 铷铁硼 is a typo for 钕铁硼.
Yes, it is obviously not very accurate (sample is not in a rage :)) but I'm sure many are excited about the possibilities and don't know Chinese (Mandarin?).
Targum translation. From the comments and video it seems he claims levitation of a micron sized particle. Not sure if it is fake or not.
