A bookseller in Chongqing has been leaving novels on trains and at stations to inspire more commuters(上下班往返的人)to read, after seeing British actress Emma Watson take part in a similar project in London.

    Author and bookstore owner Jiang Lin, 29, randomly placed 40 works along the city's light-rail system on Sunday. Whoever finds a book can read it in public or take it home, but they are encouraged to leave it again on public transportation once they have finished with it. Jiang said, “I considered the needs of commuters," he said. "I hope strangers can feel comforted by the books and feel connected with other readers."

    All 40 books were chosen from Jiang's store, Razor's Edge Book Club, which he opened in the summer, and included fiction and nonfiction, with topics ranging from art and social sciences to philosophy and history Jiang's Books on the Chongqing Light Rail project follows the same model as Books on the Underground, which was started in 2012 and sees “book fairies” leave works on London Tube trains and at stations. Readers are encouraged to share their views on the books. It was revealed on Nov. 1 that Watson, who is best-known for the Harry Potter movie series, is a book fairy.

    “After I read the news about her leaving books on the London Tube, I was so inspired that I immediately decided to do something over the weekend,” Jiang said. However, his decision was so spontaneous that he had no time to make the stickers that are usually placed on each book to identify them as part of the project . Instead, he put a note on the fly page to introduce the concept.

    To his surprise, one of his friends was among those who found his books and posted a picture on WeChat Moments, a social media function on the instant-messaging app. Jiang said more than 20 people have since come onboard and are now working on a more detailed than to spread the love of reading. Although increasing numbers of people read on digital devices, books have not totally gone out of fashion. Jiang mentioned that they needed the support from Chonqing Light Rail Co. to ensure the books to stay there and also hoped the project could be welcomed across the country.

    Here is some must-know information from a handbook on how people behave in doing business in some countries.

In Brazil

    Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (particularly women) with light cheek kisses. Schedules tend to be flexible, with business meetings sometimes starting later than planned. But to be safe, be on time. Meals can stretch for hours—there's no such thing as rushing a meal in Brazil. Lunches also can start in the mid to late afternoon. Brazilians are social, preferring face-to-face communication over mails or phone calls.

    In Singapore

    Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. Arriving late is considered disrespectful. So be on time. Efficiency(效率) is the goal, so meetings and dealings often are fast-paced. Singaporeans are direct in their discussions, even when the subject is about money. Rank is important and authority is respected. This determines both people interact in meetings. For example, people avoid disagreeing outright with someone with a higher rank.

    In the United Arab Emirates

    In the UAE, status is important, so the most senior or oldest should be greeted first with their titles. The handshake seems to be longer than elsewhere. So, do not pull away the handshake. Women should cover themselves when it comes to dress. Men also tend to be covered from neck to elbows(肘部) and down to the knees. People do not avoid entertaining in their homes, but they also hold business meals at restaurants. Touching or passing food or eating with your left hand is to be avoided. When meetings are one-to-one, if your host offers you coffee, you should refuse. It might seem odd, but it is a cultural tradition. Coffee should only be accepted if it is always set out or presented.

    In Switzerland

    The Swiss tend to be formal and address each other by last name. They also are respectful of private lives. You should be careful not to ask about personal topics. Punctuality (守时) is vital, something that comes from a deep respect for others' time. Arrive at any meeting or event a few minutes early to be safe. They also have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree. Neat, clean dress is expected. The Swiss follow formal table manners. They also keep their hands visible at the table and their elbows off the table. It is polite to finish the food on your plate.

    With the wide, application of the Internet, Uber, a new approach to your destination instead of taking an ordinary taxi, has become more popular recently. However, benefits won't come without its fair share of drawbacks. The ride-sharing experience is about to get awkward.

    Uber drivers are a part of the so-called sharing economy: They use their own vehicles, receive customer reviews via the app's five-star rating system and make their own hours and choices. Unlike other services, Uber claimed that drivers all over the country could dearly alert customers that tipping is not included. Those drivers that expect to be tipped can make their wishes known. But the company is holding to its official no-tip-required line. “Once you arrive at your destination, your fare is automatically charged to your credit card on file－there's no need to tip.” Although drivers value the freedom to push a button rather than punch a clock like ordinary taxi drivers, lack of a clear policy leaves Uber drivers m a vulnerable (脆弱的) and awkward position: If they ask a customer for a tip or put up a sign, that customer could give the driver a low star-rating, and the driver could finally be removed from the app.

    But has the company done a good job working with customers? Some observers say that this new grey area for tipping will create awkwardness about whether they should tip or not. Providing an option to tip on an app sends a clear message to customers to reach into their pockets. According to Guinn's 2015 survey of roughly 500 people, merely 30% people would be more likely to leave a tip if they were presented with a “no tip” button.

    If the service is twice as expensive during a rain storm or public transport delay, the customer has the right not to tip, However, if the driver is extra helpful or avoids traffic to reach your destination in a more timely manner, you could give an extra tip, says Uber, who will leave tipping options in the hands of the consumer rather than the app.

    My professor brother and I have an argument about head and heart, about whether he overvalues IQ while I lean more toward EQ. We commonly have this debate about people—can you be friends with a really smart jerk（怪物）?—but that also applies to animals as well .I'd love it if our dog could fetch the morning paper and then read it to me over coffee, but I actually care much more about her loyal and innocent heart. There's already enough thinking going on in our house, and we probably spend too much time in our heads. Where we need some role modeling is in instinct, and that's where a dog is a vivid example.

    I did not grow up with dogs, which meant that my older daughter's respectful but firm determination to get one required some adjustment on my part. I often felt she was training me: from ages of 6 to 9, she gently schooled me in various breeds and their personalities, whispered to the dogs we met with so they would charm and persuade me, demonstrated by her self-discipline that she was ready for the responsibility. And thus came our dog Twist, whom I sometimes mistake for a third daughter.

    At first I thought the challenge would be to train her to sit, to follow, to walk calmly beside us and not go wildly chasing the neighborhood rabbits. But I soon discovered how much more we had to learn from her than she from us.

    If it is true, for example, that the secret to a child's success is less rare genius than raw persistence, Twist's ability to stay on task is a model for us all, especially if the task is trying to capture the sunbeam that touches softly around the living room as the wind blows through the branches outside. She never succeeds, and she never gives up. This includes when she runs straight into walls.

    Then there is her unfailing patience, which breaks down only when she senses that dinnertime was 15 minutes ago and we have somehow failed to notice. Even then she is more eager than annoyed, and her refusal to complain shows a self control of which I'm not always capable when hungry.

    But the lesson I value most is the one in forgiveness, and Twist first offered this when she was still very young. When she was about 7 months old, we took her to the vet to be spayed（切除卵巢）. We turned her over to a stranger, who was to perform a procedure that was probably not pleasant. But when the vet returned her to us, weak and tender, there was no accusation, no how could you do that to me? It was as though she already knew that we would not intentionally cause her pain, and while she did not understand, she forgave and curled up with her head on my daughter's lap.

    I suppose we could have concluded that she was just blindly loyal and obedient. But eventually we knew better. She is entirely capable of disobedience, as she has proved many times. She will ignore us when there are more interesting things to look at, scold us when we are careless, bark into the twilight when she has urgent messages to send. But her patience with our failings and carelessness and her willingness to give us a second chance are a daily lesson in gratitude.

    My friends who grow up with dogs tell me how when they were teenagers and trusted no one in the world, they could tell their dog all their secrets. It was the one friend who would not gossip or betray, could provide in the middle of the night the soft, unselfish comfort and peace that adolescence plots to disturb. An age that is all about growth and risk needs some anchors and weights, a stable model when all else is changing. Sometimes I think Twist's devotion keeps my girls on a benevolent leash, one that hangs quietly at their side as they walk fast along but occasionally pulls them back to safety and solid ground.

We've weighed so many decisions so carefully in raising our daughters—what school to send them to and what church to attend, when to give them cell phones and with what precautions. But when it comes to what really shapes their character and binds our family, I never would have thought we would owe so much to its smallest member.

    When young, I loved going on trail(小路) runs. It was my favorite way to escape stress. So, when I was back in my hometown after a tough first year of my Ph. D. program, I thought a trail run was just what I needed. But instead of helping me relax, the run did just the opposite.

    After I moved to the city for college, where my runs were on flat concrete paths instead of winding dirt trails, I used a GPS watch. When I went on trail runs again in the country, it constantly reminded me of the fact that I wasn't keeping up with my usual pace. I turned my watch off, thinking that would allow me to enjoy my surroundings and find the peace I expected, but I worried I was underperforming. "Why can't I let go and just enjoy myself?" I wondered. But after some introspection(反省), I realized why I was struggling­both on trail runs and in graduate school.

    Going into my Ph. D. , I had thought that my solid undergraduate track record would set me up for instant success. To my surprise, I was wrong. I lacked confidence in my research abilities which I thought stopped me performing well and I constantly felt my progress was too slow. Other students'self-confidence and their excellent results made me feel insecure. Finally, one day I broke down in tears in my adviser's office.

    Then came my visit home: I was having trouble because I hadn't properly adjusted my expectations to the differences between an urban run and a trail run.

    A Ph. D. is like a trail run: Sometimes you can run fast. Sometimes you might find yourself climbing up a steep, winding trail at a snail's pace. And that's OK. Barriers are unavoidable, and success looks and feels different on a challenging trail than it does on a smooth, flat path. Sometimes it's best to take a deep breath and do your best to meet the challenge.
