One talented father created the tag “Dadfact” in an effort to persuade his child into eating their sandwiches using information that might not be completely reliable.

Flying is fine if you want to save time, but nothing beats the railway for a relaxing and down-to-earth journey. The Zhengzhou—Xuzhou and Xi'an—Fuzhou high-speed railways put into operation in September mark a connection of high-speed railways in China's eastern and middle-western regions, and they have brought out some of the country's best landscapes and cuisines.

    Here are four signature dishes(招牌菜) that you shouldn't miss as you travel along the railways.

Yangrou Paomo, Xi'an

    If one dish could represent Xi'an, the capital of Shaanxi, locals would tell you without doubt that it's Yangrou Paomo. It is a bowl of lamb soup served with hard flour “bread”, which is broken up and added to the soup. The soup is topped with slices of mutton, scallion(葱) and coriander(香菜). Then it is usually eaten with picked sweet garlic.

Soup Dumpling, Kaifeng

    A popular snack in Kaifeng, Henan, the dish is made up of three things: skin, meat and soup. The skin is made from flour, while the filling is usually pork. And just as its name suggests, the soup dumplings are filled with tasty soup. But how does the steaming hot soup get into the dumplings? It's actually been cooled and cut into cubes, which fit easily into the dough(面团). Along with the pork, the cubes become liquid soup once they're steamed.

Smelly Mandarin Fish, Huangshan

    Despite its name, Smelly Mandarin Fish(臭鳜鱼) is known for its good taste. A lot of travelers who visit Huangshan in Anhui want to taste it because they have heard of its reputation. Once the skin has been removed, the fresh is preserved in salty water for six to seven days, then fried and cooked in soy sauce. Although salting gives the fish its special smell, the original tender flesh is preserved well and given a delicious and unique taste.

Buddha Jumps Over the Wall, Fuzhou

    The dish has enjoyed an over 100-year-long worldwide reputation since it was invented in Fuzhou, Fujian in the late Qing Dynasty(1644-1911). Fotiaoqiang, or Buddha Jumps Over the Wall, got its interesting name from a poem a customer wrote. The poem said the dish was so delicious that upon smelling it, monks in the neighboring temple would jump over the wall to come and get some. Buddha Jumps Over the Wall is made up of many ingredients, including sea cucumber(海参), chicken, pork and mushroom. Because of these ingredients, it tastes extremely delicious while being highly nutritious at the same time.

    So what is rewilding?

    Imagine our natural habitats growing instead of shrinking. Imagine species thriving, instead of declining. That's rewilding. Rewilding is ecological restoration and a little bit more. Rewilding offers hope for wildlife, humans and the planet.

    Why is rewilding essential for Britain?

    ●Our ecosystems are broken. The places where you would expect wildlife to thrive have been reduced to wet deserts. The seabed has been damaged and stripped of its living creatures.

    ●Our wildlife is disappearing. Many wonderful British species have declined catastrophically over the past century. We've lost more of our large mammals than any European country except Ireland.

    ●We need keystone species. These vital species, including top predator（食肉动物）,drive ecological processes. Their loss in Britain and around the world has worsened our living systems.

    ●Nature looks after us. Good ecosystems can provide us with clean air and water, prevent flooding, store carbon, and attract visitors. Rewilding can leave the world in a better state than it is today.

    What are challenges?

    Our "rewilding britain" is a long-term project. Of course it has its challenges. Many of us feel indifferent, because we have got used to the lack of native forests. Many farmers oppose the idea. They thought it a crazy idea to bring back predators to the country because they would start killing farm animals. It takes time to educate them. Above all, we need money! So we need your help!

My decision to travel around China lay merely with my curiosity about the place. Before coming here, China seemed alien to me —-a place that expected to be hugely dissimilar from my own British culture.

After travelling from Beijing up to Xi'an, I wanted to challenge myself by choosing a smaller town—-Xiahe in Gansu Province. I arrived in Lanzhou at around 5 am, but there were no buses to Xiahe. I managed to spot a policeman and attempted to explain my destination to him in simple English, praying that he would understand. I wasn't sure that he did but I just followed him anyway as I had no choice. He took me on a bus and I didn't know where I was going. Luckily, I met a student who explained to me in English that the policeman was taking me to another bus station where I could take a bus to Xiahe. During this conversation a third man said he was also a policeman and would help me buy tickets. But as he was not in uniform, I was a little doubtful. The uniformed policeman told me it was OK to go with the third man, so I got off the bus with the so-called policeman who at this point, disappeared and I was left in the middle of nowhere. I stood panicking. Around one minute later a police car came and stopped right by me. It was the un-uniformed policeman. I got into the car and he dropped me directly at the bus station, and helped me buy the ticket.

    This is one of many experiences that I have had in China. I realized that however different this culture was, there was one thing that would always stand out—kindness. In the west we seem to lack the foundation of trust, yet in China it seems that there will always be someone to answer your questions and lead you the right way.

    At first, muffled (听不太清的)conversations made researchers at a San Diego aquarium puzzled, but when a diver thought he was being told to get “out” of the water they realized the conversations were coming from a white whale.

    Noc was about one year old when he was caught off the Pacific coast of Canada. He was kept in an open-ocean pen (围栏) at the US National Marine Mammal Foundation in San Diego, California. After seven years at the Foundation, he began, automatically, to make unusual sounds, a report in the latest issue of the journal, Current Biology, said.

    “We thought of the whale' s vocalizations(发出的声音) as an attempt to imitate humans. Whale vocalizations often sounded as if two people were talking just out of the range of our understanding,” the authors said. “ 'These conversations' were heard several times before we finally realized the whale was the source.” The researchers realized it was Noc when a diver surfaced and asked, “Who told me to get out?” It was then that they realized the word “out”, which was repeated several times, had come from Noc. Later, his speech-like sounds were recorded in the air and underwater.

    Noc started making the sounds after seven years in the open-ocean pen, and continued making them for another four years. He died five years ago. Researchers have now analyzed the sound recordings. It was the first time that sound recordings had shown how such sounds imitated speech and were different from the usual calls of the species.

    The speech-like sounds were lower than normal whale sounds and much closer to those of the human voice. Also, whales talk to each other by blowing air through their noses, rather than using a larynx(喉), as people do.

    “We don't claim that our whale was a good imitator compared to such well-known imitators as parrots,” the researchers said. “However, the behavior we observed is an example of vocal learning by the white whale. It seems that Noc's close association with humans played a role in how often and how well he employed his human voice.”

    When Luke went to university he thought he would be on a new journey in life and getting his own place. In the UK, it's common to fly the nest at a fairly young age. Many choose a flat-share; others make plans to get on the property ladder.

    But the current economic situation forced Luke back to his mum's house at the age of 27. And he's not alone: a quarter of young adults in the UK now live with their parents. The Office for National Statistics said more than 3.3 million adults between the ages of 20 and 34 were living with their parents in 2013.

    Lack of jobs and the high cost of renting accommodation made Luke change his plans. He's upset. "There's something very difficult about being an adult living in an environment where you're still a child," he says. "It limits me socially; sometimes I feel it limits me professionally."

    Indeed, many young people have no choice but to stay at "the hotel of Mum and Dad".

    Krissy had to return home after a year away and now lives in rather terrible conditions, sharing the family's three-bedroom house with her sisters. She says they end up getting on each other's nerves when it's time to use the bathroom in the morning.

    Of course, living with your parents is not unusual in some countries. Economic conditions, culture, or family traditions mean many young people stay at home until they get married. Even then, it can be too expensive to rent or buy a house and the married couples continue to live at one of their parents' homes.

    But some parents seem to enjoy having their kids back at home. Janice's daughters are part of what's being called "the boomerang generation". She says, "I get to share their lives with them, and I've got to know them all as adults. We have the sort of conversations that good friends do."

    So for some it's a win-win situation — spending time with your families, and saving money.
