Chinese are usually short but Yao Ming is like 7ft tall, so what? There are outliers. Jonah Hill, Adam Sandler, Jason Segal and Ben Stiller are all allegedly over 6ft tall. Also jews are notorious race mixers... And liars, many non-jewish men also lie about their height or wear shoes to make them appear taller. That's not a great basis especially if that's you're only reason you think he's not a jew.
Your first example, Yao Ming, was a Chinese experiment. The CCP made the tallest Chinese woman and the tallest Chinese man procreate. All the other examples you provided are not very tall men, which is my point. Jews are unlikely to be very tall because they're shorter than Whites. It's a perfectly good basis.
