Changbai Mountain is in Jilin Province. It’s said to be the most beautiful mountain in the northeast of China. Its name, Changbai, means “forever white” in Chinese, and its whiteness is because of the pumice stones(浮石). You can get there by train or by bus. Here are some tips for you if you want to visit it: 1. From November to April, heavy snow covers(覆盖) the area. August is the best time to visit it. 2. Be sure to start from your hotel early in the morning, so that you have enough time to see everything and return. Visitors can’t live on the mountain. 3. Bring food and water with you.
