Interestingly, the inventor of the Yawei steno theory was originally the inventor of a Gregg Shorthand theory for Chinese, which was in widespread stenographic use until he came up with the machine theory. I have attached a link to a copy (I found somewhere anonymous online) of his Yawei Shorthand theory for reference.
