Years ago I moved to Woodland Hills to take a job in a small hospital's emergency department. No one wanted to work on Christmas Eve, so the shift（轮班）went to me. I kissed my family goodbye and went off to spend the night in the hospital. It was a thankless job.

    At 9 pm, the ambulance brought in a man in his 60s who was having a heart attack. His face was pale, and he was frightened. The whole night I did my best to save his life. Before I left in the morning to spend Christmas with my family, I stopped by to see how he was doing. It was still tough, but he had survived the night and was sleeping.

    The following year I got Christmas Eve duty again. At 9 pm sharp, the ward clerk told me there was a couple who wanted to speak with me. When I approached them, the man introduced himself as Mr. Lee and said, “You probably don't remember me, but last Christmas Eve you saved my life. Thank you for the year you gave me.” He and his wife hugged me, handed me a small gift, and left.

    The following year a new doctor had joined the group, but I wanted to see if Mr. and Mrs. Lee would return. This time, I volunteered for the shift. I kept an eye on the door. Once again, at exactly 9 pm, the Lees appeared, carrying a warmly wrapped bundle. It was their new grandchild. Mr. Lee, his family and I spent 13 Christmas Eves together.

    The last year I saw him, he brought me a gift. I carefully opened the package and found a crystal bell inside. It was carved with a single word: Friendship. Now, my family, friends and I ring that bell every Christmas Eve at exactly 9 pm and offer our best wishes to the man who we won't forget.

    Christmastime in the city brings forests of trees already cut and waiting to be sold. But some people like to drive to tree farms. Others wait for their trees to come to them. They order one from the pages of a catalog or on the Internet. Some say the easiest thing of all is to buy a man­made tree with Christmas lights already on it. No falling needles to have to clean up.

    The National Christmas Tree Association says 33,000,000 real trees were sold last year, compared to 9,000,000 man­made ones. Man­made trees generally cost more, but they can be reused. Most natural trees are cut up and recycled, but some people buy trees that can be planted.

    Most Christmas trees are now grown on farms instead of in forests. Twenty-one thousand tree farmers in the United States grow Christmas trees on more than 180,000 hectares. Oregon was the leading producer last year.

    Twenty-two percent of people who bought real trees last year chose them at a farm. Two percent of those people cut the trees themselves. The next most popular places were big stores like Walmart and Home Depot. Groups like the Boy Scouts also sell Christmas trees. But some people pay nothing for theirs. They steal it.

    Cornell University in Ithaca, New York, has many pretty evergreens. Some years ago, a university worker found a way to keep them there. A month before Christmas, workers treated them with “pink ugly mix”. It contains water and red food colour. The bright colour starts to disappear after about a month. It can take longer, however. Cornell decided not to use the mix this year, but the idea has spread.

    So many of us hold on to little complaints that may have come from an argument, a misunderstanding, the way we were raised, or some other painful events. Stubbornly, we wait for someone else to reach out to us—believing this is the only way we can forgive or rekindle a friendship or family relationship.

    A friend of mine, recently told me that she hadn't spoken to her son in almost three years. She said that she and her son had had a disagreement about his wife and that she wouldn't speak to him again unless he called first. When I suggested that she be the one to reach out, she said, “I can't do that. He's the one who should apologize.” After a little gentle encouragement, however, she did decide to be the first one to reach out. To her amazement, her son was grateful for her willingness to call and offered an apology of his own. As is usually the case when someone takes the chance and reaches out, everyone wins.

    Whenever we hold on to our anger, we turn “small stuff(问题)” into really “big stuff” in our minds. We start to believe that our positions are more important than our happiness. They are not. If you want to be a more peaceful person you must understand that being right is almost never more important than allowing yourself to be happy. The way to be happy is to let go, and reach out. Let other people be right. This doesn't mean that you're wrong. Everything will be fine. You'll experience the peace of letting go, as well as the joy of letting others be right.

    You'll also notice that, as you reach out and let others be “right” they will become less defensive and more loving toward you. They might even reach back. But, if for some reason they don't, that's okay too. You'll have the inner satisfaction of knowing that you have done your part to create a more loving world, and certainly you'll be more peaceful yourself.

    They were a happy family: four daughters all in the same school in different grades. The youngest, Janice, who was in my class, seemed to be glued （粘）to her mother's skirts. The three older girls took the bus to school every morning, but Janice was always driven to school by her mother.

    One Friday, Janice's mother asked for a talk with me. She said in a soft voice, "My husband is going to Europe on business for two weeks, and he insists that I go with him. I have tried to explain over and over that Janice needs me here. But he thinks that she will be fine without me so I have no choice; I have to go. I have told the babysitter to drive her every morning. Will you please give Janice special attention and help her? I want to be sure everything goes well for her." I told her that we would make every effort to support Janice. I even volunteered to meet Janice at her car so she would see a familiar face. As a mother myself, I'd like to help. Janice's mother thanked me for our understanding.

    On Monday morning, expecting a tearful, anxious child, I planned a special program of fun and games. I waited outside to greet Janice, but just then the bus arrived and not three, but four girls got off. Janice skipped along joyfully, saying "goodbye" to her sisters as she ran with two friends into the classroom. I walked slowly into the classroom and called Janice over to ask how the bus ride went. Impatiently she said, "Oh, I always want to take the bus with the other kids, but Mother needs to be with me. You see there won't be any more babies, so I have to be a baby a little longer. While she is away, I'll just ride the bus every day. I am five, you know.

    For the first time, China's South Pole researchers can eat fresh vegetables grown regularly, according to Wang Zheng, the grower, who came home last month after a 400-day mission in Antarctica.

    "Growing vegetables in Antarctica reminded me of The Martian, a sci-fi movie about an astronaut who survives alone on Mars by eating potatoes he grows there," Wang said on Friday. "I totally understand the main character of the movie, I understand how he feels when he watches a small green plant grow in a fragile man-made environment,'' said the 40-year-old doctor. But he admitted that the conditions he faced in the Antarctic were much better than those in the film.

    Wang said the growth chamber(生长室) at the Zhongshan Station, had only a low yield when it was established in 2013. The amount was too small to make it possible for researchers to have vegetable dishes. To increase the yield, he reduced the number of vegetable varieties and focused on only some fast-growing ones, which makes the output stable. As a result, during much of his stay there, at least one vegetable dish, such as cucumbers, lettuce or cabbage, was served at every meal for a group of 18 researchers.

    Wang, an orthopedist, said he knew nothing about botany or farming before he arrived at the station in December, 2014. "I was given this job probably because my office is next to the growth chamber, and as a doctor, I had more spare time than others," Wang said. He considered many factors, such as light, temperature and humidity. Light music is played in the 16-square - meter greenhouse around the clock. "Mild music is good for vegetable growth," he said. "We also played Buddhist music, which has soft melody."

    "Growers before me did very good work. My job was to maintain the chamber and keep everything working." Before the  harvest, researchers had a very limited vegetable supply—mostly potatoes and cabbage, which taste awful after months of storage. "Because of our success in growing vegetables, we can have fresh vegetables every day," he said. "The Russian station is no more than one kilometer away from ours. We even had enough vegetables to invite our Russian colleagues for dinner."

    China's popular "Singles' Day", better known as "Double Eleven", started out as a day to celebrate singles symbolized by the four number ones on the date of November 11.

    With time that meaning has changed. In 2009, China's e-commerce leader Alibaba set the day as a lucky shopping day for online sales as the date was both easy to remember and perfectly timed as it hit between the consumer spending lull (间歇) between National Day and Chinese New Year. It soon became a hit, and Double Eleven became a buying frenzy (疯狂) spread across the world's second largest economy.

    In 2019, the Double Eleven Shopping Festival entered its eleventh year. During this decade, Alibaba, Chinese e-commerce giant, and other e-commerce platforms, together with consumers, have co-created a very big shopping event whose heat has swept the world. Foreign readers share their ideas on Singles' Day in China:

    GhostBuster (UK) I think Double Eleven is unbelievable. It is not a religious festival that people of the same religion but living in different countries share. As an e-commerce faithful fan, I really love the shopping festival.

    Emanreus (Australia) I work in Shanghai. Many of my young female colleagues are still single. They simply haven't time to date, as they tend to work long hours then travel two hours by subway to get to and from work. Single's Day is a day when they give themselves a treat with online shopping.

    BlondeAmber (Ireland) There is not hing to be proud of to be in a country that spends so much online on a particular day. It does nothing more than show the superficiality (肤浅) of the temporary pleasure of shopping, and produces nothing more than a mountain of environmental waste. I bet there is plenty of buyers' deep regret after this day.

    Ionstar (US) Singles Day became a big deal for Valentine's Day not for the singles! Well, Alibaba's 11. 11 has become more famous and important than that of Black Friday and Cyber Monday!
