What is the setting of Tripmaster Monkey: His Fake Book by Maxine Hong Kingston?

The novel is set primarily in San Francisco in 1963, with many recognizable landmarks including Golden Gate Park, the Golden Gate Bridge, Muni busses, Coit Tower, Sutro's and the Palace of Fine Arts. The narrative is laced with compelling descriptions of these locations including the hippies in Golden Gate Park, one of whom sells Wittman a peek through an empty toilet paper roll and then calls Wittman, arrayed in his Brooks Brothers suit, a "hippie dippy." Although Wittman lives in Chinatown and returns to it several times during the novel, there is no description offered. Perhaps to Wittman, Chinatown is as familiar as his own refrigerator, and no more remarkable.
