What is the source of this? Different than everything else I see online, like https://transferwise.com/au/blog/income-tax-in-china for example.
The site you linked says "source, December 2017" right under it, and if you click the link, that page says last reviewed August 2018. That site has not been adjusted to account for the new tax law. If you look at Chinese sources you will find that the beijinger is actually correct.
