Believe it nor not, ancient Chinese people had their own methods of heat preservation in winter.

    “Wen Ding”, ancient rice cooker

    The “Wen Ding”, an ancient cooking container, preserved heat by burning fuels like charcoal. The one unearthed in Nanjing in 1989 is thought to be the oldest of its kind discovered in China, dating back to the Stone Age.

    Ran Lu”, ancient small hot pot

    The “Ran Lu” is a small-sized cooking vessel (器皿) made of bronze. A charcoal stove forms the main structure, with a bottom tray to hold charcoal ashes, and a movable cup at the top. Some experts have concluded that the vessel's structure suggests that these vessels became popular in the Warring States Period (475—221 BC).

    Bronze You, ancient kettle

    The Bronze You, one of the most common wine containers during the Shang and Zhou, dynasties, could also be used to warm wine. For example, the Bronze You with beast mask design, unearthed in Jiangxi province, had an opening where charcoals could be placed, allowing people to enjoy a hot drink.

    Bronze Yan, ancient steamer

    Although the “Wen Ding” was effective at keeping food warm, ancient Chinese people later found that its burning produced pollution. As a result, the Bronze Van was made with a two-tier (双层的) structure and used to steam rice and other grains. After the Eastern Han Dynasty (AD 25-AD 220), further improvements to the Bronze Yan led to the modern day steamer.

    About three decades ago, China was known as the "Bicycle Kingdom". But later on, bikes were replaced by their fuel-powered competitors.

    But recent months have seen a recovery of the humble bike across China, with an increasing number of people choosing cycling instead of driving to schools, to workplaces or to do sightseeing. The introduction of bike-sharing schemes, pioneered by start-ups like Ofo and Mobike, has brought the trend to a new level.

    People can unlock the shared bikes by simply using their smartphone. The bikes are equipped with GPS and can be left anywhere in public for the next user. They're popular among many Chinese people as they provide an effective solution to the "last mile" problem, which refers to the final leg of a person's journey.

    " In places where the subway doesn't extend, where it's difficult to change from one kind of transport to another, it's so easy to get where you want to go with Mobike," Hu Hong,29,told AFP. She pedals(骑车)to her Shanghai real-estate job.

    However, the schemes have also led to problems such as illegal parking, vandalism(故意毁坏) and theft. Last month, two nurses in Beijing were placed under administrative punishment for five days for putting locks on two shared bikes. And in December, a man who stole a shared bike was sentenced to a 3-month detention(拘留),and fined 1 ,000 yuan by the Shanghai Minhang People's Court.

    " Bike-sharing is a greener method of transportation and provides a user-friendly experience,"said Liu Xiaoming, vice-minister of transport.

    " But it's a combination of online and offline business. Operators are usually strong in online services, but lack offline business experience, which causes problems."

    Now, Chinese service operators are trying to solve the problems. For example, a bike- sharing company called Mobike sets a 100-point credit score for each user, with points taken in the case of bad behavior. Once a score drops below 80, bike rental is increased to 100 yuan per 30 minutes, up from 0.5 - 1 yuan.

Dear Graham,

    My partner and I have recently lost a pet quite suddenly. Normal life is continuing with so much sadness for my pet meant so much to me. Lots of people won't understand my feeling this way about the death of an animal. This obviously isn't the first time someone in my life has passed away: when I was younger we lost elderly relatives who I loved very much, and naturally much-loved family pets died occasionally too. But this has hit me so much harder. I put so much love into the relationship and I'm just finding it hard to get my head around the fact that it's gone.

    Thank you for taking the time to read this.

ANON, VIA EMAIL

Dear Anon,

    Something you loved deeply has gone from your life, so of course you are sad. We love our pets differently from family members or friends and part of that is because we know they will probably die before us. Our time with our dogs or cats is precious precisely because we understand it is limited.

    As humans, we go through most of life understanding we would die one day. But animals don't. We are the keeper of the secret. Of course, living a life unencumbered(不受妨碍) by thoughts of death means that our pets, in general, lead very simple, happy lives. It's one of the reasons why they are such a joy to be round. You are, of course, correct when you say that many people don't understand your grief, so don't talk to them. Share your feelings with like-minded souls. I'm sure a simple search online will reveal many practical advice for moving on.

    And when you are ready, you can welcome another animal into your life and then you will enjoy happiness again.

GRAHAM, VIA EMAIL

    I have three kids and a great husband and I'm enjoying a career that I find challenging and fun. To the outside world, this feels like" Success." But there is still a voice in my heart asking if this is who I truly am. Only in silence do I hear the self and wonder who that person might be.

    So I booked a trip to find out. I travelled, for the first time, without my husband or kids. I went to Iceland with a friend, who shares an appreciation for wilderness and silence.

    For six days, we were immersed(沉浸)in wild, raw scenery and real weather—a11 kinds of weather. Climbing a mountain against rain and returning to a tent for a simple meal reminds you how little you actually need. And how strong it feels to be uncomfortable sometimes.

    I found silence in Iceland, and time to consider the me outside of career and the me out—side of kids as I shared stories with strangers.

    When I stopped talking and just 1istened, I became more generous. I 1earned that choosing to be generous can create more space, more food and more warmth.

But I didn't really gain any better appreciation of what I want from life or my job. I suspect the anxiety that drove me to seek silence in Iceland was losing sight of my ability to choose gratitude and joy, and to be present in the challenges I set in my career and my family.

    I came home to noise, rush and love; with no less confusion on who I want to be. I know the answer isn't waiting out there on the top of a mountain in Iceland. The answer is in front of me with every step on my own life's path, and in every choice I make.

    Electronic book publishing has many of the same risks and opportunities as electronic music publishing. By delivering text direct to the reader's computer screen, the e-book could cut down costs, and allow creators to deal directly with their audience, by passing (绕开) traditional publishers and traders. But it also raises the possibility of mass piracy (盗版). Phil Rance, founder and managing director of Online Originals, a London-based e-book publisher, sums it up, "No one wants Napster (在线音乐服务) to happen to books."

    Indeed, the most popular MP3may have put the frighteners on an industry that generally operates some way behind the "bleeding edge". The Meta Group, a leading US-based market researcher, says publishers are far too concerned about protecting their rights, "We believe all the recent legal control over Napster is like putting a finger in a river that is already overflowing. Publishers need to deal with reality and come up with new ways to develop wide electronic distribution, asking the question: How can we use the certainty of wide distribution to our advantage."

    At the moment, most publishers would like to limit the use of e-books to the person who bought them, or to the computer used to download them. If that can be done, e-books become just an extra income stream in a publishing industry that would continue to operate the way it does today, according to Terry Robinson, business manager for Adobe's e-paper group. "If you've cracked the digital rights aspect, you've cracked the market." He says.

    Robert Nichols, Books Director at BOL agrees, "Rights management is absolutely important. Publishers just say that 'until copyright is secure, we are not going to talk'."
