Last summer, my friend and me visited Beijing’s Hutongs, which made us have the deep understanding of Beijing. The Hutongs mainly built during the Ming and Qing dynasties. Nobody know exactly how many Hutongs there are in Beijing. If we connected all Hutongs together, and the total length would even be long than the Great Wall. As is known, the Great Wall is about 4,000 mile long. Some Hutongs are such narrow that a person like me, in order to get through, has to walk sideways. And some Hutongs have more than 20 turns. With our delight, some are well preserved, where we can experience typically life of old Beijing locals

Recent, we have discussed the ways of traveling. Here is a result. Some students choose to travel with a group. With a guide help, they won't get lost and they don't need to look up for hotels by themselves. Besides, they can make friends and help each other while take a trip.
However, other students prefer travel alone. That's why they can arrange their time freely and choose to visit their favorite tourist spots. What's more, it's a chance for us to learn to look after themselves.
For me, I'd like to travel alone. I wanted to spend enough time visiting the place where I like. In this way, I can enjoy my vacation better.
