Constantinople and Chongqing are the same job description: a heavily defensible city at the head of a long civilizational corridor, with a population large enough to need its own dialect and small enough to feel besieged. Constantinople held the eastern Mediterranean against everything for a thousand years. Chongqing held wartime China against Japan when Nanjing and Wuhan fell. Both are gigantic, vertical, fog-bound, and proud of how spicy their food is.君士坦丁堡与重庆，是同一份职位描述：长走廊源头的一座重防御之城，人口足以拥有自己的方言，又小到永远感觉「在被围攻」。君士坦丁堡顶住东地中海一千年；重庆在南京、武汉沦陷后顶住战时中国。两地都巨型、垂直、雾气缭绕，并以自家饮食的辣劲为豪。
