Uhm, this piqued my interest, so I looked into it
The article clearly explained the reason behind the up to 5 hours wait:
1) the family members who were trying to claim the ashes of their loved ones showed randomly without making appointments
2) the crematorium is facing a severe shortage of workers
3) due to both reasons above, it took a long time for the workers to locate ashes
Hence the up to five hours wait for some of them
Of course, the tweet does not mention any of this
The person tweeting seemingly prefers to instead use the up to five hours wait as "evidence" that "evil China" is lying about its numbers
The second tweet is even worse?
It does not provide any sources for any of its claims, and it looks as if the person pulled her numbers from some YouTuber?
