I (ethnic Chinese) went to China with two friends from Texas in the early 2010s. One of them has long blonde hair. She was never stopped in Shanghai, a couple of times in Beijing, but in Chengdu, they were just so amazed by her and her husband (but mostly her and her long blonde hair). People wanted to take pictures with my friends.
Maybe things have changed a lot since then but worth a try! Chengdu is definitely worth visiting and I'm sure there are many very interesting more inland cities in China to visit (and maybe be a celebrity for a moment).
Once we got to the smaller, interior towns, we had to be really careful with our movement, as we could attract dangerously large crowds just by going to the morning market or the like. The vast majority of people were just curious, and I have a lot of happy memories of smiles and connections, but a few of coming close to getting killed, too.
Still, risk is everywhere, and the positives win out. I loved learning what I could, and I hope meeting us was a net joy for the folks we interacted with, too.
What happened to your eyes?
Just going to the suburbs of Shanghai will do it.
It was the touristy parts of Beijing where I got the most attention. Usually from tourists from more rural parts of China, or museums with lots of bussed in schoolkids.
