The city skyline rises day by day, glass curtain walls stand in rows, and neon lights dazzle, building a prosperous modern urban picture. The world is intoxicated by the grandeur of high-rise buildings, preferring the exquisiteness of commercial districts and streets, while I, who likes trading coins and being alone, uniquely love wandering through the urban villages in the folds of the city, touching the most vivid pulse of a city among the crisscrossing alleys, feeling the warmest smoke of the human world. 'Moth eyebrows, snow willows, golden threads, laughing and talking, fragrant shadows fade away' this is the smoke human world.
