      Have you noticed your life becoming a little easier? Now, when you go to a certain shopping mall, you can enjoy its free Wi-Fi there. When you want to take a taxi, you can book one with your phone. In fact, all these can be seen as the basic parts of a smart city.

     The idea of a smart city was brought up by US company IBM in 2010. Generally, a smart city is a city that uses digital technologies such as the Internet to improve city planning, save money and resources, and make our life convenient. How smart can a city be? Here are great examples that we can learn from.

      In 2009, Dubuque became the first smart city in the US. The city used smart water meters to take the place of traditional water meters. They can detect（探测〉water waste and leakage（泄漏）and send data to let the house owner know. The same system is used for other city resources like electricity and natural gas. This way, people know how they use their resources and are glad to help reduce waste.

       Santander in Spain also gives us a look at the future. If people point a phone toward a nearby bus stop, the phone immediately shows all bus lines that serve the stop as well as their arrival times.

    As I was leaving to meet Lynne, my roommate told me that I'd better take some money. But I didn't listen to him. I thought that Lynne would pay because she had invited me. I arrived at the restaurant exactly on time. I'd been told that Americans expect you to be on time. Lynne and I sat at a table in the corner of restaurant and a waitress came and took our order.

    The dinner was a great success. I talked a lot about Saudi Arabia and Lynne told me all about herself. After two hours, the waitress finally came and asked if we wanted one check or two. Lynne said two. We went to the cashier and Lynne paid her check. I was embarrassed (尴尬) when the cashier gave me my bill. I had no money to pay for my meal. Then I had an idea. I pretended to look for something in my pockets and said, “Oh! I forgot my wallet! Can I call my roommate, please?” The cashier showed me where the phone was and I quickly called my roommate. In a few minutes, he arrived with some money, but he couldn't hide how he felt. He laughed all the way home. Now, I think it's funny too, but at that time I was terribly embarrassed. I thought that an invitation to have dinner in the United States meant the same thing as that in China. I guess you have to understand that your customs are only your customs. When you visit a foreign country, you have to learn about their customs, too.

The Double Third Festival, also ancient Shangsi Festival is an ancient Chinese festival. It comes on the third day of the third lunar month, so It's not on the same day every year. The day is said to be the birthday of Yellow Emperor （Huangdi）. It didn't have a fixed date until the Wei and Jin dynasties（朝代）.

In the Eastern Jin Dynasty, people often bath in the river on that day to wash away bad luck. Wang Xizhi wrote in his Lantingji Xu- about how people took a bath and wrote poems while drinking. In the Tang Dynasty, people enjoyed drinks and sightseeing. In the Ming and Qing dynasties, people did activities like throwing stones, going for long walks in the country and listening to music.

In modern times, people in the southern parts of China mainly celebrate the festival. For the Zhuang people in Guangxi, they can enjoy a two or three- day holiday. And it is a festival for young people to sing songs and find their true love. Bamboo dancing is another important actıvıty for them. For the Li and Miao people in Hainan, it is a day for remembering ancestors （祖先）. For the Han people, it is a time to go outside to enjoy flowers and cook eggs with jicai. The Han people believe the wild vegetable and the special eggs are of great benefit to human health. In some areas, there are dragon boat races and other cultural performances to celebrate this lucky day.

All in all, the Double Third Festival is a time for people to feel nature, share traditions, and celebrate the arrival of spring with joy.
