Thanks. I'm aware of this! I just used Xi a bunch and didn't want to keep typing Xi Jinping either so I used Jinping. Changed up the pronoun for readability and variety.
Is it culturally unacceptable to refer to Xi Jinping as Jinping?
It's culturally about the same suddenly referring to Obama as Barack. As in, unless you are actually on a first-name basis with the person, you wouldn't do it.
