Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their cooperation and support, passing around necessary nutrition “depending on who needs it”.

    Nitrogen (氮) and carbon are shared through miles of underground fungi (真菌) networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons (神经元) in our brains, and when one tree is destroyed, it affects all.
     Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest
   “We didn't take any notice of it.” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    A story of a man who made the brave journey of love, cycling from India to Sweden to see his sweetheart, has gained the hearts of thousands online. A Facebook post, that has been linked more than 113,000 times, shares the tale of how Dr. Pradyumna Kumar Mahanandia crossed eight countries to be reunited with his wife Charlotte Von Schedvin in her native country.

    The story began in 1975 when wealthy 19-year-old Charlotte Von Schedvin, who was a student in London at the time, travelled to India in 1975 to meet the poor but famous artist Mahanandia. The Indian was born in 1949 into a poor family in Odisha, Dhenkanal and was considered an untouchable in the society.

Although his family couldn't afford his education, he managed to gain a place at the College of Art in New Delhi where word of his talent quickly spread.

    In events that wouldn't be out of place in a romantic movie, when the young Charlotte Von Sledvin met with the painter, the two fell in love with one another. He was greatly impressed by her beauty and she, with his pure simplicity. Despite their contrasting backgrounds, the pair shortly married.

    In 1978, the time came for Charlotte to return to her native country, and she requested her husband join her back in Europe. However, Mahanandia was in the middle of his studies and said he would join her after these were completed. The couple stayed in touch through letters and despite Charlotte's offers to send flight tickets, Mahanandia was determined to meet her in his own way.

    Selling his belongings, he managed to get enough money to buy a second-hand bike and set out on the intrepid journey to be reunited. From New Delhi, the brave love-struck adventurer entered Afghanistan, Iran, Turkey, Bulgaria, Yugoslavia, Germany, Austria and Denmark. It wasn't all easy sailing. His bike broke down a lot of times along the way and he had to go on without food for days.

    In total the trip took four months and three weeks before he finally reached Gothenburg, Sweden. Upon arrival, he was questioned by immigration officers, who were said to be amazed at his story of devotion after he shared photographs of his marriage.

    Her parents welcomed him with open arms and 40 years later, the pair are still happily married. Dr PK Mahanandia serves as the Odiya Cultural Ambassador of India to Sweden and lives with his wife and two children in Sweden. He has become well-known in Sweden as an artist and as an adviser of Art and Culture, under the Swedish Government too.

    The American Academy of Pediatrics (AAP) (儿科学) just released its updated guidelines for children's media use.

    The recommendations reflect what all parents know: children need less screen time, which indicates that they desperately need more free time to develop their imagination, a sense of wonder and discover their passion and purpose.

    Our children are over-stimulated, over-scheduled and under pressure to perform academically and beyond school. This weakens their ability to build creative thinking skills essential to self-discovery. Creativity occurs when kids have time for curiosity and exploration. With children spending up to eight hours a day on media devices and additional hours engaging in scheduled activities, opportunities for growth disappear.

    What we are not so sure about is how to get our kids to want the free, screenless time which we know will benefit them. It may sound counter-intuitive (违背直觉的) but today's kids need coaching to experience and discover the benefits of free time.

What came to parents easily a few decades ago has become a challenge for our generation. It's not that yesterday's parents knew more about child development; they simply had fewer choices. Boredom and relaxation were an inescapable part of daily life. Today, they mean, "I'm a bad parent and not doing enough to get my kid ahead."

    Recently, I had an eye-opening revelation while watching my 11-year-old daughter play in a softball game. I have six children and have attended dozens of such game. I know the drill—or thought I did. Families settled in for the day with lawn chairs, cold drinks and cousins. These brothers and sisters would gradually chat with each other. Games of catch and hide-and-seek began, and friendships were formed then. At crucial moments, the newfound friends turned their attention to the field to cheer on their teams.

    But that wasn't happening. Though there were at least 15 children by the sidelines (球场边线), I didn't hear any of them. They sat in silence using their individual tablets (平板电脑). Even with the score tied in the final inning (垒球比赛的一局), not a single child watched the game or spoke to each other. The situation was strange and revealing: Kids have more planned activities and passive entertainment at their fingertips than ever before, but less free time to dream, imagine and focus on what they truly love.

I understand that making time for "nothing" is difficult in a world where we are constantly worried our kids will fall behind if they aren't good at academics. But I refuse to sit back and watch this loss of childhood. We are taking back childhood. Imagination needs time and space to blossom.

If your kids are like mine, asking them to imagine will at the beginning be difficult. That's because they haven't developed the skills and muscle memory to make it second nature. I hope the AAP guidelines prompt all of us to set needed screen time limits for our children. Personally, I am practicing strategies to "develop imagination" in my children. Imagination, like a sport, requires practice, training, motivational speeches, rewards and extreme patience.

    In China we can see more African students in universities, which is a signal of a deeper China-Africa relationship, and the same trend is happening in Africa as well. Most Chinese students choose to study in universities in South Sudan, Egypt, Kenya, Ghana, Ethiopia and South Africa.

    There are three types of Chinese students in Africa. One type is language students who major in local African languages such as Swahili in China and go to African countries to study the language. Another type is non-language students who major in law, economy, culture, education or agriculture and go to African universities for six months to a year to learn more about the culture or for research. The above two types of students are all funded by Chinese government.

    A third type has been growing in recent years. More Chinese choose to develop their career and build a life in African countries, and some of their children tend to receive higher education in African countries. Some Chinese who work in Africa also further their study in their free time. Many Chinese choose to join the MBA program, since they work in a Chinese state-owned enterprise, and an MBA degree could help advance their career.

    In addition, as China and Africa's relations and cooperation are heating up and more Chinese companies and investors come to Africa under The Belt and Road Initiative(一带一路), more talents that understand Africa are needed. Besides, the new generations have more internationalized, curious attitudes, and are more willing to see and experience Africa themselves without any stereotypes(刻板印象), rather than just reading about it in a textbook.

    Visual language is a form of communication that uses visual elements (元素) as opposed to formal written language to convey meaning or an idea, Graphicacy, the ability to communicate visually, is considered as important as literacy and numeracy, the abilities to read and count. Some people are visual thinkers, using that part of the brain that is emotional and creative to process and give meaning to information. Visual communication can find expression in paintings, drawings, symbols, or simply lines and shapes arranged for a specific effect.

    Art is an example of visual language. A painting or sculpture can convey ideas or arouse specific kinds of emotional responses. It may also express ideas about historical events, abstract concepts, or simply be about the way certain shapes or forms "work" together or create a certain effect on the mind. Some researchers believe that different parts of the brain respond in unique ways to colors and shapes.

Pictograms (象形文字) and ideograms (表意文字) are types of visual language. Pictograms are pictures that are similar to what they represent. They are still used today to communicate information. Many people around the world are familiar with the pictograms indicating such things as airports, public facilities, and non-smoking areas indicated by a cigarette in a circle with a line across it. Ideograms are pictures that represent ideas and can often be understood without the aid of written language. Some scholars track modern alphabets to pictures Letters are actually ancient pictures, and words are a series of pictures. Modern alphabet letters are not only phonetic (语音的) symbols but are based on ancient religious images and symbols.

    Musivisual communication is also a part of visual language. The term refers to music created specifically to improve the visual experience of film. It corresponds to the images being seen on the screen, and the music may arouse a sense of terror, fear, or other emotions. Most movie goers understand the language of musical clues showing that something dramatic or important is about to happen.

    A couple had a son eleven years after they married. They were a loving couple and the boy was the apple of their eye. When the boy was around four years old, one day the father was very tired after work so he asked his wife to pick up their son. The mother, who was very busy in the kitchen, totally forgot about it.

    Later the boy lost his way on the street. When the son was found missing, the mother hurried to look for him, but she didn't find him. The mother felt very sad and didn't know how to face her husband.

    When the father went to the police station after hearing that the son was missing, he looked at his wife and said just four words. What do you think the four words were? The husband just said "I love you, darling."

    The son was missing. If he had picked him up earlier, this would not have happened. There is no point in blaming (责备) anyone. His wife had also lost her only child. What his wife needed at that moment was comfort and understanding from her husband. That is what the husband gave his wife. Several weeks later, with the help of the police, the couple finally found their lost son. The family's relationship became stronger over that time.

    Sometimes we spend lots of time asking who is to blame. We miss many chances to give each other support and let each other feel the warmth of human relationships. Get rid of all your unwillingness to forgive, selfishness, and fears and you will find the world is much more wonderful.
