What is the main idea of the second paragraph? 1 For the past five years, I’ve lived about a mile north of the Forbidden City in an apartment building off a tiny alleyway in downtown Beijing. My alley has no official name, and it begins in the west, passes through three ninety-degree turns, and exits to the south. Locals call my alley Little Ju’er, because it connects with the larger street known as Ju’er Hutong . 2 I live in a modern three-story building, but it’s surrounded by the single-story homes of brick, wood, and tile that are characteristic of hutong . These structures stand behind walls of gray brick, and often a visitor to old Beijing is impressed by the sense of division: wall after wall, gray brick upon gray brick. But actually a hutong neighborhood is most distinguished by connections and movement . Dozens of households might share a single entrance, and although the old residences have running water, few people have private bathrooms, so public toilets play a major role in local life. In a hutong , much is communal , including the alley itself. Even in winter, residents bundle up and sit in the road, chatting with their neighbors. Street vendors pass through regularly, because the hutong are too small for supermarkets.
