The ending of Lu Xun's " Medicine " depicted a desolate and dilapidated city. They looked at the courtyard in the wilderness and could not help but feel a little disheartened. Although this courtyard was not small, it looked like it had been abandoned for many years. It was overgrown with weeds and some trees had even fallen down. The ground of the courtyard was covered with a thick layer of dust, as if it had not been cleaned for a long time. Even at night, it was very quiet here. Only the occasional chirping of birds could be heard. It depicted a desolate and dilapidated urban environment, indicating that the city where the story took place had not been taken care of for a long time and had become dilapidated. This kind of environment also hinted that the actions of the pharmaceutical factory owner and others were irresponsible. They only cared about their own interests and did not care about the health and lives of others.
