That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week away, I was still learning my lines. I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.

    As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers. Very few people were still out except a few sad-looking homeless people under blankets.

    About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.

    Suddenly I wasn't cold or tired anymore. I ran out of the door and back to where I'd heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found. Just as I was about to give up the search, I heard the garbage truck(垃圾车) pull up to the sidewalk next to me. When a voice called from the inside,  "Alisa Camacho?" I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eye. "Is this what you're looking for?" he asked, holding up a small square shape.

    It was nearly 3 a.m. by the time I got into bed. I wouldn't get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn't be a bad place as long as people were willing to help each other.

    The annual World Economic Forum (经济论坛) took place in Davos, Switzerland, in Jan. 23-26, 2018. What did Chinese entrepreneurs (企业家) speak in the forum? Are there some quotable quotes for you?

    Jack Ma, founder and executive chairman of Alibaba Group

    "I think globalization cannot be stopped — no one can stop globalization, no one can stop trade. If trade stops, the world stops. Trade is the way to dissolve (溶解，结束) the war not cause the war," said Ma in Davos, "Google, Facebook, Amazon and Alibaba — we are the luckiest companies of this century. But we have the responsibility to have a good heart, and do something good."

    Richard Liu, founder and chief executive officer of JD

    "Business is not only a way to make money but also a way to contribute yourself, to help people," Liu said in a speech in Davos. "How can we face the fractured (分化的) world? That's the topics of the Davos this year. I think a very important thing in business is cooperation. If we can unite, work together, if we work very closely, I think we can bring more hope to the people and we can build more trust between the people, countries and companies and partners," he said.

    Jane Sun, CEO of Ctrip

    "Tourism is a sunrise industry. Since I entered Ctrip, every year there are new comers, which, first of all, shows that tourism is booming." Sun told Sina.com in Davos. "We invested heavily in ABC. A refers to AI, B is big data, and C is cloud computing. As we continue to expand overseas, these three will be very good weapons for us. So we think those mean opportunity," she said.

    Hu Xiaoming, president of Aliyun

    "In 2018, people will see the development in various countries more closely connected with cloud computing. More manufacturing enterprises and financial institutions will start to use 'cloud', and cloud computing will increase the efficiency of technology and finance," Hu told Xinhua in Davos.

    Over 500 dogs being delivered to a butcher house were saved by a Chinese animal protection organization.

    The incident then triggered a debate among Chinese netizens about the necessity of pouring so much money and efforts into saving dogs.

    On Friday, a truck loaded with over 500 dogs were stopped by volunteers from animal protection organization on Jingha Expressway Beijing section. Beijing Times reported these dogs were being delivered to slaughter houses in the city of Changchun, northeast Jilin Province and would be eventually served on dinner tables. After negotiations with the truck driver, pet service provider Leepet Holding Corp. and a philanthropic foundation, Shang shan Foundation purchased these dogs, each paying 50,000 yuan. Dogs were then delivered to the headquarter of China Small Animal Protection Association (CSAPA), being taken care of and waiting for adoption.

    After the "dog saving mission" was reported, Chinese net users debate over whether saving dogs is worth so much efforts and money while there are still many poor and needy people in China lacking assistance. Some net users argue the "dog saving mission" is placing overattention to animals while lots of needy people are still left unattended. A microblogger "Xiaowulaitajie" said on China's twitter like website, weibo.com, "Dogs are saved, adopted and they attracted media spotlight. We'd better spend such money and take such efforts in helping the needy people." Another microblogger, Liluping, said "We poured such huge sum of money into saving dogs. I would rather the money was spent on disaster relief."

    Some applaud volunteers' actions and show eagerness of offering their helping hands to those saved dogs.

    Still many disapprove those "saving dogs" critics, but they argue that such act nonetheless promotes social progress.

    A microblogger named "broken bridge" said, saving dogs does not run counter to taking care of people. Such enthusiasm in public affairs will help raise social awareness in helping the needy.

    I think people and animals are created equal. Attention should be paid to people as well as animals.

    Golden Gate Bridge

    Located in San Francisco, the Golden Gate Bridge started in the year 1933 to connect the San Francisco Peninsula with Marin County. It was finally thrown open to public traffic in 1937. It cost $25.7 million in the construction. Till the year 1957, the Golden Gate Bridge, at a length of 2,737 meters, was the longest suspension bridge in the world.

    Brooklyn Bridge

    The Brooklyn Bridge is located in Brooklyn. It is one of the oldest suspension bridges in the United States, having been opened in the year 1883. The length of the bridge is 1,843 meters. The bridge has been featured in several Hollywood movies.

    George Washington Bridge

    Also known as the Hudson River Bridge and the Columbus Bridge, the George Washington Bridge which connects Fort Lee to Manhattan came into use in 1931 after a construction period of almost 4 years. It is a two level suspension bridge that cost about $52 million to build.

    Mackinac Bridge

    This is the third biggest suspension bridge in the world at a length of 8,038 meters. The architect of this bridge was Dr. David B. Steinman, who directed the construction of the bridge which started in the year 1954 and opened to the public in 1958. People using this bridge are charged a certain amount of money.

Navajo Bridge

    Located in Arizona, this bridge crosses the Colorado River and is almost 250 meters long. The construction of this bridge started in the year 1927, ending two years later, costing $390,000. In the 1990s, a second bridge was built which was opened to the public in 1994. The first bridge is now used only by pedestrians.

    I've come back to check on a baby. Just after dusk I'm in a car down a muddy road in the rain, past rows of shackled (戴镣的) elephants, their trunks swinging. I was here five hours before, when the sun was high and hot and tourists were on elephants' backs.

    Walking now, I can hardly see the path with my phone's flashlight. When the wooden fence post stops me short, I point my light down and follow a current of rainwater across the floor until it washes up against three large, gray feet. A fourth foot twisted above the surface, tied tightly by a short chain and choked by ring of metal spikes (尖刺). When the elephant gets tired and puts her foot down, the spikes press deeper into her ankle.

    Meena is four years and two months old, still a child as elephants go. Khammon Kongkhaw, her caretaker, told me earlier that Meena wears the spiked chain because she tends to kick. Kongkhaw has been responsible for Meena here at Maetaman Elephant Adventure, near Chiang Mai, in northern Thailand, since she was 11 months old. He said he keeps her on the spiked chain only during the day and takes it off at night. But it's night now.

    I ask Jin Laoshen, the Maetaman worker, why her chain is still on. He says he doesn't know.

    Maetaman is one of many animal attractions in and around tourist-crowded Chiang Mai. Meena's life is set to follow the same track as many of the roughly 3,800 captive (被捕获的) elephants in Thailand. When Meena is too old or sick to give rides—maybe at 55, maybe at 75, she'll die. If she's lucky, she'll get a few years of retirement. She'll spend most of her life on a chain.
