In the summer of 1988, travelling from Dengshikou, in the center of Beijing, to the Xiyuan Hotel, just across from the Beijing Zoo, seemed like travelling to the outer edge of Beijing. I was back in Beijing visiting my host family at the end of the summer, and they were worried about me travelling so far on my own. But I had an invitation to dinner with an American professor, and my host family reluctantly let me travel across Beijing on the electric trolley bus to attend the dinner.
