2. It is best to climb at 5 or 6 pm. Don't be too anxious. It's almost 3 or 4 o'clock in Tianjie. After a short rest, you can go to watch the sunrise on the Japanese platform. When you watch the sunrise in summer, you must watch the weather forecast. It must be sunny, cloudy and rainy, so I can't see it. In addition, you should bring water and thick clothes to climb Mount Tai at night.
