This has nothing to do with mongering. If you want a good massage, some Chinese cities have massage facilities that have sight-impaired or even blind masseuses. I was told that they have a gift of being able to sense problem areas much better when you get a massage. I believe this is true because on one trip last year, a local Chinese friend took me to such a place. I had a chronic tight muscle problem in the lower back worked out and it's been good ever since. Inexpensive too (like $2 for 20 minutes). I was never able to have that done in the States.
