An 80-year-old man was sitting on the sofa in his house along with his 45-year-old highly educated son. Suddenly a crow (乌鸦) landed on their window.

    The father asked his son, “What is this?”

    The son replied, “It is a crow.”

    After a few minutes, the father asked his son for the second time, “What is this?”

    The son said, “Father, I told you just now. It's a crow. ”

    After a little while, the father again asked his son the same question for the third time, “What is this?”

    This time, the son said to his father in a low and cold tone, “It's a crow, a crow.”

    After a moment, the father again asked his son for the fourth time, “What is this?”

    This time the son shouted at his father, “Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW'. Are you not able to understand this?”

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page. The following words were written in it.

    Today my little son aged three was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I didn't at all feet angry, but instead felt affection for my son.

    So...

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. Be considerate to your parents.

    With these tips you can finally get a solid night's sleep.

    Reserve Your Bed

    Get into bed just for sleeping. Avoid working, paying bills, reading, or watching television in bed. If you associate your bed only with sleep, you'll be more likely to fall asleep.

    Watch the Caffeine(咖啡因)

    Too much caffeine throughout the day can cause interrupted sleep. Limit yourself to two cups of tea, coffee, or cola, taken at least 6 hours before bedtime.

    Tap the Exercise Answer

    In a study from Stanford University School of Medicine, a group of 50- to 76-year-olds who had complained of sleep problems began proper exercise for about half an hour four times a week. Compared with a similar group of people who didn't exercise, the more active group slept an average of one hour more each night, took less time to fall asleep.

    Take a Bath

    Take a warm bath an hour or two before bed. Your body temperature will slowly drop after you get out of the tub（浴盆）, making you feel tired. Don't bathe right before bed, however, because it can briefly stimulate you enough to make it hard to fall asleep.

    Buy the Right Bed

    A bed that's too soft can cause poor sleep. Replace your mattress(床垫)if it's more than ten years old, and buy one that's as firm as you can tolerate but still comfortable.

    If 30 minutes go by and you haven't fallen asleep, don't lie in bed feeling frustrated. Get up and do something relaxing.

    It's nice to have people of like mind around. Agreeable people boost your confidence and allow you to relax and feel comfortable. Unfortunately, that comfort can hinder the very learning that can expand your company and your career.

    It's nice to have people agree, but you need conflicting perspectives to dig out the truth. If everyone around you has similar views, your work will suffer from confirmation bias (偏颇).

    Take a look at your own network. Do your contacts share your point of view on most subjects? If yes, it's time to shake things up. As a leader, it can be challenging to create an environment in which people will freely disagree and argue, but as the saying goes: From confrontation(冲突) comes brilliance.

    It's not easy for most people to actively seek conflict. Many spend their lives trying to avoid arguments. There's no need to go out and find people you hate, but you need to do some self-assessment to determine where you have become stale(疲沓的) in your thinking. You may need to start by encouraging your current network to help you identify your blind spots.

    Passionate, energetic debate does not require anger and hard feelings to be effective. But it does require moral strength. Once you have worthy opponents, set some ground rules so everyone understands responsibilities and boundaries. The objective of this debating game is not to win but to get to the truth that will allow you to move faster, farther, and better.

    Fierce debating can hurt feelings, particularly when strong personalities are involved. Make sure you check in with your opponents so that they are not carrying the emotion of the battles beyond the battlefield. Break the tension with smiles and humor to reinforce the idea that this is friendly discourse and that all are working toward a common goal.

    Reward all those involved in the debate sufficiently when the goals are reached. Let your sparring partners (拳击陪练) know how much you appreciate their contribution. The more they feel appreciated, the more they'll be willing to get into the ring next time.

    As computers become more popular in China, Chinese people are increasingly depending on computer keyboards to input Chinese characters. But if they use the computer too much, they may end up forgetting the exact strokes of each Chinese character when writing on paper. Experts suggest people, especially students, write by hand more.

    Do you write by hand more or type more? In Beijing, students start using a computer as early as primary school. And computer dependence is more widely spread among university students. Almost all their assignment and essays are typed on a computer.

    All the students interviewed say they usually use a computer.

    It's faster and easier to correct if using a computer. And that's why computers are being applied more and more often to modern education. But when people are taking stock in computers increasingly, problems appear.

    "When I'm writing with a pen, I find I often can't remember how to write a character, though I feel I'm familiar with it."

    "I'm not in the mood to write when faced with a pen and paper."

    Many students don't feel this is something to worry about. Now that it's more convenient and efficient to write on a computer, why bother to handwrite?

    Many educators think differently. Shi Liwei, headmaster of a famous primary school in the capital said, "Chinese characters enjoy both practical and aesthetic value. But those characters typed with computer keyboards only maintain their practical value. All the artistic beauty of the characters is lost. And handwriting contains the writer's emotion. Through one's handwriting, people can get to know one's thinking and personality. Beautiful writing will give people a better first impression of them."

    To encourage students to handwrite more, many primary schools in Beijing have made writing classes compulsory(必修的)and in universities, some professors are asking students to turn in their homework and essays written by hand.
