you will never know with Chinese, there are a lot of fake news and lots of exaggerated news. these mining farms in China are one of the main reasons most of the electricity provides (specially the small ones) are alive, the government can not just cut them off and kill a large business like this and put hundreds or possibly thousands out of job. that will have a big impact on their economics. bitcoin mining is not just some dude in his underwear in the basement mining bitcoin, it has actually created lots of jobs and sustains lots of businesses.
as for solar panels, it is possible but it is always so much easier to transfer your farm to some place else out of the jurisdiction!
