Walking toward the National Museum of China we met Bo Jin, a 30 year old art student, in the street. Outgoing, with an engaging grin and fast, clipped English, he wanted to help us with directions. He told us the National Museum was closed today because of US vice president Biden's visit and would reopen to the public tomorrow. He suggested we go on to visit the Forbidden City instead. We told him our daughter, who is near his age, is also an artist and teaches at a University in Tennessee. "Oh, that's very good," he said brightly. "Now she can care for you when you are old!"
