If I were an English author writing for a Chinese institution, the first thing I would do before publishing to the world is have my entire paper checked for spelling, grammar, syntax, and readability. It's cheap to have a Chinese-speaking editor, and/or to use AI—especially if that's your field—so why isn't it happening?
This paper, like nearly all other papers written by Chinese authors, is unacceptable, and should not have been published as-is. Even the primary example, turned into a hero viz, is grammatically nonsensical.
Appalling, and inexplicably occurring nearly every time.
