It's rare that the protagonist in a Chinese movie wins the audience's hearts with an emotionally uplifting message, rather than by showing off his or her good looks. But Wolf Warrior II is putting China in the global spotlight. It's also the first film to taste success both in terms of box office earnings and promoting Chinese values.

    Kung fu artist Wu Jing both starred in and directed the action movie. Since its release on July 27, it's earned an unimaginable 4.5 billion yuan, setting a record for domestic movies at the box office. The success of the film has surpassed the anticipations of all, including the production team.

    The film focuses on a rescue operation in Africa, led by former special forces soldier Leng Feng-played by Wu. Leng helps Chinese workers and local Africans flee a war-torn and plague-ravaged country. Wolf Warrior II links art to reality, and reminds people of the massive evacuation of Chinese people from Libya when civil war broke out there in 2011, and from Yemen in 2015, as well as the challenges the Ebola virus created in West Africa from 2013 to 2016. The film describes how the Chinese government aims to protect overseas Chinese citizens. Just as the message at the end of the film reads: “Citizens of the People's Republic of China. When you encounter danger in a foreign land, do not give up! Please remember, at your back stands a strong motherland.”

    Thanks to China's increasing participation in global affairs, now could be considered the right moment to introduce a modern Chinese hero.

    “Holding up a banner of peace, friendship and responsibility, Wolf Warrior II should be seen as a brave effort to promote Chinese values around the world,” columnist Zhu Ping wrote in China Daily.

    “It's time Chinese filmmakers produced films that tell good stories and carry the right spirit. Let us assume Wolf Warrior II has started that trend.”

    It's a warm summer afternoon. You're cooking up the catch of the day over a campfire. Suddenly, a few raindrops fall on your arms, and before you know it, the sky is opened up. Then you hear what sounds like thunder in the distance. What should you do? Your tent is close by and would offer shelter from the pouring rain. There's a campsite picnic shelter a few minutes down the path. And then you remember that your car is parked down the road. What's your safest choice to make sure you and your families are safe?

    It's a common question for many hikers(徒步者) and campers, especially when they are camping during summer months. Heading to your car is almost always the safest choice. Your tent and a picnic shelter will keep you dry, but they offer little or no protection against lightening. Your car, on the other hand, will keep you dry and protect you from lightening strikes. Protecting yourself against possible lightening strikes is very important; lightening kills an average of 62 people in the US each year. If you keep all of the windows and doors closed in your car, you'll be able to return to your campsite safely.

    Of course, if you're backpacking(背包旅行), not car camping, and you're deep in the woods, your car won't be a good choice. So, what should you do if your car is far away and there's no other safe shelter nearby? First, you'll have to make sure that tree limbs or other objects don't fall on you or your campsite. Then you'll have to get in a safe position to avoid lightening, or flash flood conditions. What else should you do?

    Most kinds of rose plants come from Asia. But roses are also native to other areas including northwest Africa, Europe and the United States. Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts.

    You should plant your roses where they can get sunshine for about six hours on bright days. You can buy roses from a garden center or by mail order. You can buy potted（盆栽）roses, also known as container roses, or bare-root（裸根）plants. Each kind has its fans.

    Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, president of Nature Hills Nursery in Omaha, Nebraska, points out that bare-root roses come without soil. So they weigh less to transport. If they arrive before you are ready to plant them, make sure the packing material is slightly wet. Keep the plants in a cool, dark place. You plant the roses while they are not active. The resting plants have no leaves but still need water.

    When growing roses, the soil should be wet. Watering should be done in the morning. That can prevent problem called black spots. But do not water too much. Jeffrey Dinslage says people often ask him about becoming discolored on rose leaves. He says the problems are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch（覆盖物） from around the roots for a short time. This will help dry the soil. If your soil is very dry, you can add compost(堆肥), which returns nutrients（营养）to the soil.

    We often seek food after focused mental activity, like preparing for an exam. Researchers guess that too much thinking consumes a lot of energy from the brain. So the brain, sensing that it may soon require more calories to keep going, apparently leads to bodily hunger, and even though there has been little physical movement, we eat.

    The researchers note that tiring activity both increases the amount of blood sugar and lactate(乳酸盐)circulating in the blood and increases blood flow to the head.

    Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel—rich blood during exercise could feed a worn—out brain and reduce the urge to overeat.

    Thirty—eight healthy college students were invited to determine their fitness and metabolic(新陈代谢)rates and to report what their favorite pizza was. Afterward, they sat quietly for 35 minutes before being given as much of their favorite pizza as they wanted. At a later date, the volunteers returned and spent 20 minutes making selections from college and graduate-school entrance exams.

    Next, half the students sat quietly for 15 minutes, before being given pizza. The rest of the volunteers spent those 15 minutes doing intervals on a treadmill(跑步机)two minutes of hard running followed by about one minute of walking, repeated five times. These students were then allowed to gorge on pizza, too. But by and large, they did not overeat.

    When the researchers factored in(将……作为因素考虑)the calories burnt on running, they determined that those students actually consumed 200 fewer total calories after their brain workouts than the resting students.

    The researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as running, although the researchers say they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hungers call.

    Donald was not very good at math. He could not understand the teacher's explanations. Even when the teacher explained something a second time, Donald still could not understand it. "Never mind," Donald told himself, "I'm quite good at other subjects. I'll cheat in the math exam, and then I won't be in trouble."

    "I will sit next to the boy who's good at math,'' he thought, "and copy down his answers." The day of the exam came, and Donald sat next to Brian Smith, who was always at the top of the class in math. Donald carefully copied Brian's answers onto his own exam paper. At the end of the exam, the teacher collected the papers and graded them. Then she said, "Well, boys and girls. I've decided to give a prize to the student who got the highest grade. However, it's difficult for me to decide who to give the prize to, because two students, Donald and Brian, got the same grade."

    "Let them share it,'' one of the other students said.

    "I have thought about that,'' the teacher said, "but I have decided to give the prize to Brian." Donald was angry when he heard this. He stood up and said, "That is not fair. I got the same grade as Brian." "That is true," the teacher said. "However, Brian's answer to Question 18 was 'I don't know', while yours was 'Neither do I'."

    I'm a speaker and give hundreds of speeches every year. I spoke about appreciation (感激) last month and I used this quote by Albert Schweitzer "Sometimes our light goes out but is blown again into flame by meeting with another human being. Each of us should express the deepest thanks to those who have relighted this inner (内心的) light."

    I asked my audiences to shut their eyes and think about someone who, at some time in their lives, has relighted their inner light. Then I left the room in silence for several minutes. It was always a meaningful experience as they remembered the joy they felt from another person.

    One day, a gentleman came up to talk with me and thanked me for creating a new awareness (意识) in him. He said he thought of his eighth-grade history teacher because she was everyone's favorite teacher and had really made a difference in all of their lives. Several days later, the gentleman found his history teacher and he wrote to her. The following week he received this letter:

    Dear John,

    You will never know how much your letter meant to me. I am 83 years old, and I am living all alone in one room. My friends are all gone. My family's gone. I taught 50 years and yours is the first "thank you" letter I have ever gotten from a student. Sometimes I wonder what I did with my life. I will read and reread your letter until the day I die.

    The gentleman was sad, "She is always the one we talk about when we have a get-together. She is everyone's favorite teacher—we love her! But no one had ever told her until she received my letter…"
