In my general mooching about that I've been doing on Youtube, I've been amazed at how much research has already been done. I've also seen two guys, one South African and one American, who have a channel called ADV China and they discuss quite a lot of China related things including a look at job adverts at Wuhan University for two research scientist, subject Corona viruses and that was back in November.
One thing they identified was something that has gone on for years, China is sending young people overseas, usually the US, Australia and their job is to buy stuff where they can. It became more obvious because a Chinese woman in the U.S.,
Hexin Jiang, videoed herself buying a trolley load of masks, in fact she cleared the store out, she openly boasts about getting all the masks before the Americans could. She would then send them back to China where they are sold at profit. They actually drive round and cleared out most shelves in the U.S. The video is dated January just before they knew what was coming. What she didn't bargain for was the scorn that she received from her fellow Chines persons everywhere. She brought shame on her country. Just google her name if you're interested.
