    Great changes have been taken place in my village. Ten years ago, the small and low houses of my village lie on the north of a lake. The villagers produced many waste. As a result, the lake was serious polluted. To the west of the village was a sandy field, where was the source of much dust.

    Now the poor house have been replaced by green trees. However, the sandy field that the villagers used to plough has been covered of fruit trees. On the lake, now clean and clear, the villagers often spend their spare time fish.

    In word, my village has become a green one.

    I recently posted a picture on Facebook from the movie Mad Max, a film where two groups race through the desert in steam punk vehicles, and wrote, “Actual picture of my way to work today.” It was meant to be a joke because of the sandstorms in Beijing, but one of my friends from back home thought it was real.

    I couldn't imagine how they could think that is actually what China is like. China has so many more conveniences and advantages than the West, and many of my friends agree. “I don't know how I will be able to deal when I go back home,” said a friend who is about to end her gap year in Beijing. “I've become so spoiled in China.”

    China seems to be leading the way in innovation and convenience for daily life. Back home I could never shop, pull out my phone and scan a QR code to pay.

    There have been rumors of starting bike sharing in my hometown for years with little success while bike sharing suddenly appeared in Beijing overnight. I just step outside and scan a code, and I am on my way.

    Going out to eat with a group of friends back home was troublesome for both the group and the servers. Splitting checks and swiping(刷) 10 different cards or making change for each person in the group can be a pain. But with China's WeChat, you can quickly send your friends your part of the bill.

The list goes on…

    When I first arrived in Beijing, I was dead set on leaving in a month. That month has come and gone. Now, when someone asks me when I'm coming back, I think to myself, “Who knows?”

    While my friends think I'm riding through the desert on a motorbike, I am actually taking a “Didi” for what is the equivalent of $5 in the US.

    With all the conveniences and technology here, I may never want to go back.

    This happened several weeks ago. On my way to work, I accidentally got on the wrong bus because I was1the news on my phone. I had to2and walk several blocks to work, a path I had never taken.

    I met a man sitting on a bench looking very 3 so I asked him what was wrong. He said his4had been dragged away (拖走) from a public lot and that he had no5to get to the airport to meet his wife. I told him that I could help him out and let him6there.

    I went to the7one block away and got cash. When I returned, the man was standing there, watching me8him. When I gave him the cash, he hugged me, thanked me, and started9!I nearly cried, too. I wished him to get to the airport safely, explained10he could take public transport to get there, and then continued to go to my office.

    I11at my usual restaurant for a to go (带走的) breakfast and, at the door, I met another man who12said, “Excuse me, sir. I don't want your money,13could you please help me get some food?” I said, “Of course, please come with me. ” I 14my breakfast and paid for this man's order. I15him a wonderful day.

    As you may16I was so thankful for putting 17on the wrong bus at the right time. This let me18two people who needed help and19. During each meeting, I never felt afraid; I only felt20to help them.

    One day. One lifetime. You can do it! From the museum of modern art to the museum of ancient articles, visit our picks for the world's best museums.

National Gallery of Canada (Ottawa)

    This museum has a great collection of art spanning the Middle Ages to the present day, including American, Indian, European, Inuit and Canadian works. It offers a unique, near-complete overview of Canadian art — from early Quebec religious work, through Inuit work from the 1950s, to the contemporaries.

Tokugawa Art Museum (Japan)

    The Tokugawa family reigned over Japan from 1600 to 1868. Under them, the country enjoyed the longest period of peace in its history. This time span is also known as the Edo period, during which the arts flowered in Japan. Artists of this period directly influenced Western masters such as Monet, Gauguin and Whistler and have since gone on to become household names. Other exhibits effectively present, through accurately reproduced environments, aspects of Japanese life at the time.

    Museum of Fine Arts (Boston)

    Highlights of this museum's collection include a 4th-century Christian marble bust (半身像) of St. Paul at prayer, and a painting that questions life and our very existence, Gauguin's “Where do we come from? What are we? Where are we going?” It's a must — go in the US.

The Egyptian Museum (Cairo)

    As well as gathering together some of the finest archaeological finds from all Egypt, this museum also provides a rare opportunity to simply pop in and within minutes be standing face-to-face with one of the greatest works of mankind, Tutankhamun's golden mask. A portrait of unbelievable quality, craftsmanship and beauty, the highly polished gold face — at once a god, a king and a teenager — shines like water: delicate, yet untouchable all at the same time.
