Read the passage and answer the question. Amy lives in a small city in the north of China. Winter there is long and cold, and it often snows. Amy doesn't like going out in such snowy weather, so she usually reads at home. But she loves spring best. In spring, the snow melts and the weather becomes warm and sunny. Amy often flies kites with her friends in the park. Summer is hot and rainy, and autumn is cool and windy. Question: Why does Amy usually stay at home and read in winter?
