There's a lot of foot massage in Beijing.
One day, after hours of teaching and walking around, I wanted to get a foot massage. but almost all the places I passed had women with high heels and fishnet stockings on and not much else. These were the "plus plus" massage parlours and not for us women....

BUT I was turned on to a great visually impaired masseur named David (see him with his wife and son here). He does a lovely shiatsu type massage (fully clothed with no plus pluses). You can find him by crossing the street in front of the Lido Holiday Inn and going into the park. He's on the left side of the street about 50 meters in.
