I’m no expert but I think translation technology has become pretty impressive now (like real-time camera image-to-text transation), and besides, there are plenty of tourist groups for China (if you can tolerate that kind of thing). I know a few people who couldn’t even tell you the words for “one ticket, please” who visited and enjoyed China, even a few more rural areas where most locals couldn’t speak a word of English either.

(Of course, it’s basic manners to at least learn super basics like “hello” and “thank you”, and these visitors did)
