Mandarin
加以进了几回城，阿Q自然更自负，然而他又很鄙薄城里人，譬如用三尺三寸宽的木板做成的凳子，未庄人叫“长凳”，他也叫“长凳”，城里人却叫“条凳”，他想：这是错的，可笑！

Moreover, after Ah Q had been to town several times, he naturally became even more conceited, although at the same time he had the greatest contempt for townspeople. For instance, a bench made of a wooden plank three feet by three inches the Weichuang villagers called a "long bench." Ah Q called it a "long bench" too; but the townspeople called it a "straight bench," and he thought, "This is wrong. How ridiculous!"
