What should Hunan people pay attention to in terms of diet and weather when they go to work in Beijing?

The difference is not ordinary. During the Spring Festival in Hunan, the cotton-padded jacket took off its long trousers and began to spend the spring. I caught a cold directly in Beijing within two days. The third day, it snowed in Beijing. In terms of climate, the spring in Beijing will wait until the end of March, but it is already spring in Hunan after coming out for the New Year several times, so remember to bring some thick clothes, especially after March 15, Beijing will stop warming, but it is not very cold in March, but it is much colder than in winter.
