What should I prepare to go to Beijing in August, such as sunscreen, how to decide the route, and whether the hotel will fly together or take the high-speed train?

See where you are, and then according to your own economic strength, if possible, I personally suggest that you choose to fly back together or take the high-speed rail or train. . . It's up to you. . The route depends on where you want to go. If you go by yourself, you can set up a free route on Ctrip. Of course, you can also arrange the route first. Then book a hotel in a compromise or convenient transportation place. . You can also visit youth hostels in Beijing, which are everywhere. Recommended places for backpackers all over the world. Beijing is bigger. . It's definitely impossible to live in the same place. I think I have to change it. And it depends on where you go and how many days you play. . If it really doesn't work, you can go to the local tour guide. .
