You're rushing to work and a man ahead of you falls down on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people keep on walking.

    "There is a tendency to decide that no action is needed," says a psychologist, "In order to take action, you have to work against them." Here are some common thoughts that stop you from helping.

    ●Why should I be the one? I'm probably not the most able person in this crowd. You might think someone older or with more medical knowledge should offer assistance.

    ●What if he doesn't really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.

    ●No one else looks concerned. We can follow the people around us, but most people tend to hold back their emotions in public.

    "If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on," says the psychologist. "Then retry to involve other people; you don't have to take on the entire responsibility of being helpful. Sometimes it's just a matter of turning to the person next to you and saying, 'It looks like we should do something.' Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you."

    Art museums are places where people can learn about various cultures. The increasingly popular “design museums” that are opening today, however, perform quite a different role. Unlike most art museums, the design museums show objects that are easily found by the general public. These museums sometimes even place things like fridges and washing machines in the centre of the hall.

    People have argued that design museums are often made use of as advertisements for new industrial technology. But their role is not simply a matter of sales—it's the honouring of excellently invented products. The difference between the window of a department store and the showcase in a design museum is that the first tries to sell you something, while the second tells you the success of a sale.

    One advantage of design museums is that they are places where people feel familiar with the exhibits. Unlike the average art museum visitors, design museum visitors seldom feel frightened or puzzled. This is partly because design museums clearly show how and why mass－produced products work and look as they do, and how design has improved the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something beyond their understanding.

    In recent years, several new design museums have opened their doors. Each of these museums has tried to satisfy the public's growing interest in the field with new ideas. London's Design Museum, for example, shows a collection of mass－produced objects from Zippo lighters to electric typewriters to a group of Italian fish－tins. The choices open to design museums seem far less strict than those to art museums, and visitors may also sense the humorous part of our society while walking around the exhibits.

    A new restaurant in Indonesia is on a mission (使命) to support locals trapped in poverty, many of whom are earning less than $25 a month, by providing them with an alternative way to pay for their food.

    The Methane Gas Canteen, run by husband and wife team Sarimin and Suyatmi, is located in an unexpected place for an eatery — Jatibarang Landfill. The landfill is a mountain of purifying waste, where poor locals spend their days collecting plastic and glass to sell. Meanwhile, the couple, who spent 40 years collecting waste before opening the restaurant, is busy cooking.

    What makes the restaurant unusual, aside from its location, is that no cash is required to pay for meals. Poor people have the option to pay for their food with recyclable waste instead of cash. Sarimin weighs the plastic customers bring in, calculates its worth, and then deduct that value from the cost of the meal, giving any extra value back to the customer. The scheme is part of the community's solution to reduce waste in the landfill and recycle non-degradable plastics.

    “I think we recycle 1 tonne of plastic waste a day, which is a lot. This way, the plastic waste doesn't pile up, drift down the river and cause flooding,” said Saimin. “It benefits everyone.”

    The restaurant seats about 30 people and serves meals that cost between $0.40 and $0.80 each. Since opening the canteen Sarimin and Suyatmi have seen their daily income more than double to $15 a day.

    “I'm happy to see our customers enjoying their meals,” Sarimin told NHK World. “The poor must also have the right to enjoy healthy eating. I want to give them that chance as much as possible.”

The Peony Culture Festival of Luoyang

    Spring is time for people to go out and see blossoming flowers. Luoyang in Henan, China is famous for peonies, the city's official flower. The city's annual Peony Culture Festival begins in early April and lasts till early May. Peonies are in full bloom during the event, which was first held in 1983.

    You can go to the Luoyang National Peony Garden. The peonies there are known for their rich colors and long florescence. Don't miss the 1,600-year-old "Peony King"!

    Chinese Language Day

    Chinese is one of the six official working languages of the United Nations. The LIN has set different days for these languages to promote their uses. It holds exhibitions, shows and other activities. In 2010, the first Chinese Language Day was held on Nov. 12. But since 2011, it has been held on April 20. The date is close to Grain Rain, one of the 24 solar terms. It means "rain of millet". People celebrate Grain Rain to remember Cangjie, a mythical character. Many people believe that Cangjie was the first person to write Chinese characters. When he did this, it rained millet and saved people from hunger.

    China Astronautics Day

    On April 24, 1970, China's first man-made Earth satellite — Dongfanghong I — went into space. It was a big step for China's space program. In 2016, the government set April 24 as China Astronautics Day. Many events are held across the country to celebrate this special day. For example, astronauts and scientists will give talks to students. Some cities will hold exhibitions about space development.

    Last year, China had big plans for its space program. On December 8, it launched its second lunar rover（月球车）as part of the Chang'e 4 space mission, which landed on the far side of the moon.
