In the morning we went to the other side of of the city, to the neighborhood of the Central Music Conservatory, to rent a piano. You can get them from 120 RMB per month, if you sign up for a year. The Yamaha piano sounded softer though, so an upgrade to 150 RMB (18.76 EUR or 24.40 US$) per month was very appropriate. It includes a piano chair and a cloth cover. Delivery is free, tuning (any time needed) included. Let me put this into relation: it's about what I would pay for my mobile phone package per month (if I would pay for it). For the price of an iPhone 5, you can rent a piano for nearly 3 years. Usually iPhones break after one year tough. The economics of happiness is an interesting one.
