Li Cheng, an ordinary clerk in the city of Beiping, squeezed onto the clanging trams every day, traveling from the pigeon coop in the south of the city to the concrete buildings in the north, earning just enough money to get by. Life was like a donkey pulling a millstone, going around in circles, with no end in sight.
On this day, Li Cheng returned home from work, as usual, exhausted, like a toad that had been drained of its strength. He entered the house, turned on the light, and the bright white bulb illuminated the four white walls, empty and desolate, revealing a sense of shabbiness. He took off his shoes, plopped down on the hard wooden bed, and stared blankly at the wall.
