Okay so if you're getting that from this page it's apparently from a fanmade project. Before I realized this I got really freaked out because it references a 2021 game by Ubisoft Shanghai set in China during WWII and I thought I was legitimately getting Mandela effect'd because I'd never heard of this in my life. Then I looked a little closer at the url and the fact that it was "available for PlayStation 5, XboxNEXT, and PC, with a planned release on Nintendo WiiPlay in 2022" which made things pretty clear.
But a moderate faction one if I recall. One that wanted an alliance with the Assassins.
EDIT: Yeah, Sun Yat Sen was a Templar reformist, Mao is indicated to be either with Sun Yat Sen's faction or an Assassin depending on the source.
Chiang Kai-shek was a hardline templar ally, but betrayed the Templars and the Assassins and is generally considered an awful person.
Eagerly awaiting the next AC installment to see how Deng fits into all this
Deng Xiaopeng is canonically mentor of the Chinese Brotherhood of Assassins, like his predecessor Zhou Enlai.
EDIT: Apparently not canonically, see below. Still let's go with this.

Ah, I'd assumed that was a comic I'd not read that was related to the Black Cross series that has Sun Yat Sen.
