Sometimes ago, I was in Shanghai, China. On the street, quite a number of shoe shine boys, with them their shoe shinning tools, begging people to shine their shoes for 1 Renminpee.
Among them, there was this elderly China man who is around 65 years old, pulling the sleeve of a prospecting customer. I felt pity to this elderly man and I paid him 1 Renminpee for shining my shoes.
This man works because he wants to or he has to?
