Nineteenth-century London truly was a city of fog: every household burned coal for heat.
Tips
culture
Chongqing's fog rises from its two rivers and settles in the mountain basin; the city's other nickname is 山城 'Mountain City'. London's fog was coal smoke, the setting of Dickens's Oliver Twist, whose Chinese title is 雾都孤儿 'orphan of the foggy city'.
mistakes
Read 都 here: 'city, capital', as in 首都. It is not 都 'all'.
