We all know that the Vanilla version of Flash Player is reaching End-of-life on December 31 2020 in about two months, but does that date also extend to the Mainland Chinese version of Flash Player called Adobe Flash.cn?
I ask this question because many Chinese internet companies & services in addition to the Chinese Government aren't willing to spend the time, money or resources necessary to migrate from the aging Flash Player to HTML5 due to minor incompatibility problems with their services.
Once again, I live in the United States and not in China, So unless an Adobe moderator confirms that the Flash.cn version of Flash Player also end on December 31 2020, let me know.
I'm a forum moderator and Adobe product user in the US and I cannot answer that question, sorry. A flash content provider in Mainland China would probably know more about it.
That said, HTML5 is nothing new. When the major browsers started blocking Flash Player 2-3 years ago, I welcomed it without a fight and never looked back.
Apparently, according to this article, the "China Special Edition" is the only exception of the EOL of Adobe Flash, if anyone can confirm it.

Since the Chinese Government aren't going to spend the time, money, and/or resources necessary to migrate from the aging Flash Player to HTML5 & HTTPS anytime soon, many Chinese internet services are stuck in HTML4 & HTTP for a long time, mostly likely due to their Internet Censorship firewall, hardware & software (for mainly Chinese servers) being incompatible with HTML5 & HTTPS.
