every western transit designer should be required by law to visit one or more major east asia cities to see how they do it. I've been a few places in taiwan, RoK, japan and even as a non-local language speaker the transit was super easy to use. lots of colour coding on paths to guide you around and signage was really good too. this was 10+ years ago now but these cities definitely set the bar to me. I'm curious what modern transit looks like in mainland china, I've never been.
