Ching Chow Chung- In American Memory
Ching a ling a loo- In American Memory. As children we had a variant on this one, about a Chinese laundryman. Too long ago to remember the words.

Many western towns had a Chinese who broke away from the Chinatowns and set up a business, often a restaurant, a bath house or a laundry. In many cases it was a lonely life for him, or, if he had one, his family.
