You can love them or hate them, but no matter which tourist destination you visit, chances are you'll see someone with their head buried in a Lonely Planet guidebook.

    Lonely Planet is one of the world's largest travel guide brands, publishing more than 500 different guides in eight languages. The popular brand also produces television shows, websites and podcasts (播客) all devoted to travel.

     Some people praise Lonely Planet books because they make traveling easy and affordable. They also save time and make sure you don't miss the best things.

    They also provide the reviews of hostels, hotels, restaurants and ticket information about your destination.

    This can be great if you're a nervous traveler, or if you haven't traveled by yourself before. If you're in a country where you don't speak the language, sometimes there's nothing better than getting into a taxi and opening up a guidebook. You simply point to a map that directs the taxi driver to a hostel that's cheap and clean, with friendly staff and cold beer.

    But others criticize Lonely Planet and other travel guide publishers like them. They say guidebooks take the fun and spontaneity (自发性) out of traveling, and that part of the enjoyment of travel comes from the fact that anything can happen. They also regret that if you follow a guidebook, you'll end up doing the same thing and having the same experience as everyone else. You might end up seeing the same group of people over and over, because everyone is reading the same book and following the same route.

    Another criticism of travel guides is that they have a large impact on local communities. For example, some locals devote their lives to behaving in ways that attract tourists. They pretend to live a traditional lifestyle, wear traditional clothes and live in traditional houses in order to attract the tourist dollar.

    The Peales were a famous family of American artists. Charles Willson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His life-size portrait of his sons Raphaelle and Titian was so realistic that George Washington reportedly once tipped his hat (脱帽打招呼) to the figures in the picture.

    Charles Willson Peale gave up painting in his middle age and devoted his life to the Peale museum, which he founded in Philadelphia. The world's first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings Peale found the animals himself and found a method to make the exhibits more lifelike. The museum's most popular display was the skeleton (骷髅) of a huge, extinct elephant, which Peale unearthed on a New York farm in l801.

    Three of Peale's seventeen children were also famous artists. Raphaelle Peale often painted still lives of flowers, fruit, and cheese. His brother Rembrandt studied under his father and painted portraits of many famous people, including one of George Washington. Another brother, Rubens Peale, painted mostly landscapes and portraits.

    James Peale, the brother of Charles Willson Peale, specialized in miniatures (小画像). His daughter Sarah Miriam Peale was probably the first professional female portrait painter in America.

    Many people may not find the idea of visiting Beijing's Forbidden City just to see its cultural relics(遗迹)very exciting. But what if you got to see deer there too? That certainly sounds like a better day out.

    Nine deer were introduced into the Forbidden City, also known as the Palace Museum, on Sept. 26 and would make it their home until February. The beautiful animals are part of an exhibition on deer-related relics, including furniture, clothes and artworks. In ancient China, deer patterns(图案)could be seen on lots of items since lu—deer—were considered to be a lucky animal because the Chinese word shares the pronunciation(发音)of the character that means “official salary(俸禄)”.

    The deer in the Palace Museum are not only to be part of the exhibition, but also to act as ambassadors(大使)to attract visitors. “It's a better way to bring cultural relics closer to the people,”explained Wang Yamin, a deputy director at the Museum, according to ChinaDaily.

    Turning itself into a zoo is the latest effort that the museum has made at introducing academic(学术的)art to ordinary people.

    In 2014, for example, the museum's online store started to offer products such as T-shirts featuring the pattern of an emperor's coat, and earphones looking like the necklaces worn by ancient officials. These products soon gained popularity on social media because they allowed people to wear a piece of history.

    Two years later, the TV series MastersintheForbiddenCity(《我在故宫修文物》)lifted the mysterious veil(面纱)on the experts who work in the museum—people whose job is to repair the relics within it. And while many of us may have imagined these workers to be old and boring, they're actually quite young and interesting. Some are even in their 20s. They lead a peaceful career, although it can sometimes be dull. Workers aren't allowed to wear any make-up or do their nails(指甲)because the chemicals(化学物质)may damage the relics they're working on, for example.

    Little by little, the Palace Museum is shaking off the stereotypes(刻板印象)of being an old-fashioned academic institution. As Shan Jixiang, the museum's director, once said, “Academic research is not alien from the public's interest. We'd like to make visiting the museum a part of people's daily lives. ”

    It looks like the Forbidden City isn't so forbidden after all.

    A couple in their 60s has travelled 12,000 miles across 16 countries from Britain to China - riding their bikes all the way. Grandparents Peter and Chris stepped on the long journey after deciding to "do something a bit different". They traversed (横穿) cities, deserts, mountains and everything in between across Europe, the Middle East and the East Asia.

    Peter, 66, said the moment they finally had a look at the famous Great Wall after a year and a half of cycling 30 miles a day was "really exciting". At the end of their journey, the special pair didn't fly home but instead choose to book a cabin (舱) inside a 400m-long ship.

    "You never know what the day is going to bring. All you know is that you are going to get on your bike and cycle. Every day is an adventure and every day is new. Overall, the experience is unbelievable," Peter said.

    At first Peter and Chris set out to cycle from Britain in January 2017 but were forced home. They had cycled all the way to Hungary when Peter slipped and broke his leg. After seven months of recovery, the couple set out again in Britain. They finally arrived in China in November 2018.

    Both Peter and Chris agreed that the best part of the entire trip was coming across the kindness of strangers along the way, many of whom invited the couple for food and drink. Chris, 64, said, "It was a wonderful experience, particularly wonderful because of the amazing people we met along the way."

If a president, a philosopher, and one of the best-selling writers credited the same secret for their success, would you try to follow it too? What if the secret was something you already knew how to do? In fact, you probably do it every day. Here's what Friedrich Nietzsche wrote: "It is only ideas gained from walking that have any worth. " Thomas Jefferson: "Walking is the best possible exercise. " Charles Dickens: "If I could not walk far and fast, I think I should just explode and die. "

Researchers have found quite a lot of connections between walking and producing ideas. A Stanford University study found that participants were 81 percent more creative when walking as opposed to sitting. According to the study, walking outside-compared with on a treadmill (跑步机)-produces the most novel and highest-quality ideas.

The movement aspect of walking is obviously key. Our creative thinking is triggered (触发)by physical movement, which is exactly why walking-with your dog, a friend, or alone-feeds creative thinking.

The scenery is almost as important as the sweat. Breaking your routine with a walk can be a catalyst for fresh understanding of problems or projects. Just by going outside, you are stepping out of your familiar surroundings and your comfort zone, which is necessary if you want to open your mind to new possibilities. You can walk through a tree-filled neighborhood. You can walk through a park and observe people joking or birds singing. Being inside, you're more likely to be lifeless, which means you don't have enough energy to wonder or create.

So instead of setting a fitness goal, why not set a creativity goal that starts with walking? Involve yourself more closely in your surroundings. Tum off your phone and give yourself the chance to be present in the world, to hear conversations and natural sounds, and to notice the way people move and the way the sun reflects in puddle (小水坑).

Spending all day glued to your smartphone probably isn't doing you any favors. Too much phone use has been linked with a range of concems, including sleep issues, joint pain and even relationship problems. But if it's radiation you're worried about, experts say you don't have to ditch your phone. 

"There's no risk of anything hazardous or dangerous with radiation from cellphones, "said Gayle Woloschak, an associate dean and professor of radiology at the Northwesterm Univerity Feinberg School of Medicine. As with all cellphones, along with Wi-Fi networks, radio stations, remote controls and GPS, smartphones do send out radiation, said Emily Caffrey, an assistant professor of health physics at the University of Alabama at Birningham. They use invisible energy waves to transmit voices, texts, photos and emails to nearby cell towers, which can carry them to almost anywhere in the world. But nearly three decades of scientific research has not linked such exposures to medical issues like cancer, health authorities including the Food and Drug Administration say. Here's what we know. 

"Radiation"describes many types of energy, some of which do carry risks, explained Dr. Howard Fine, director of the Brain Tumor Center at NewYork —Presbyterian Weill Cornell Medical Center in New York City, "It is often sent out from radioactive substances", Atomic bombs, or, to a far lesser degree, X-ray machines, send out energy called ionizing radiation that in high enough or frequent enough amount can damage DNA and cause cancer, Dr. Fine said. 

But smartphone energy falls into a category called non-ionizing radiation, Dr. Caffrey said, which isn't powerful enough to cause this damage. "A lot of people think‘radiation is radiation, 'but it's not all the same, "Dr. Woloschak said. "There's no DNA damage seen from cellphone use. "

Most experts and health authorities like the F. D. A. and World Health Organization agree that there's no evidence that smartphone radiation causes health problems. Still, several studies over the years have made headlines for suggesting their links to brain diseases. Many of these studies have since been proved to be false, Dr. Fine said, including those focused on fifth-generation.
