When it comes to cultural heritage protection, the Grand Canalof China is probably the world's greatest project of its kind. The big inland waterway system in thenorth-eastern and central eastern plains passes through eight of the country'spresent-day provinces.

The Canal runs from Beijing in the north to Zhejiang Province inthe south. Constructed in sections from the 5th century BC onwards, it wasdesigned as a means of communication in the 7th century AD. The Canal is the world's greatest civilengineering project before the Industrial Revolution.

The Grand Canal reached a peak in the 13th century, providing aninland navigation(航行) networkconsisting of more than 2,000 kilometers of artificial waterways, linking fiveof the most important river basins in China, including the Yellow River and theYangtze. It entered a bid as a UNESCO(联合国教科文组织) culturalheritage site in 2008.

The Grand Canal cultural square is located in Beijing's Tongzhoudistrict. Ever since the Yuan dynasty 800 years ago, the Tongzhou section ofthe Grand Canal has been the life blood of Beijing. Grain and buildingmaterials were all transported to meet the endless demands of the big cities.Even today, the Grand Canal plays a major role in the lives of its citizens.

"I grew up near the Grand Canal. In the past the waterwaywas a lot narrower, but now it's nice and wide and bridges are built over it. Ithink if the bid for world heritage status succeeds, it will greatly makeTongzhou more famous in the world, especially with Tongzhou aiming to be asub-center of the capital Beijing," a citizen said.

The result of the bid is set to be released next week, and nodoubt it will certainly make it into the history books if the Canal is listedas a world heritage site.

    If you have a long holiday to spend, where can you go?

    Nikoi Island, Indonesia

    Less than 85 km-but somehow a whole world away-from Singapore's shining skyline lies Nikoi Island. Surrounded by white sandy shorelines and vivid coral reefs, Nikoi's centre is hidden in rainforest, resulting in amazing biodiversity seen in its native plants, animals and bird life. Marrying traditional Indonesian craftsmanship with contemporary design, Nikoi boasts just 15 stilted（建于支柱上的）beach houses, all with breathtaking sea views, guaranteeing privacy and total escape from the daily routine.

    Amanpulo, Philippines

    The only property on Pamalican Island, the luxurious Amanpulo resort offers extremely impressive accommodation, with only access to over five kilometres of clean coral sand beach. Designed to resemble local Bahay Kubo homes, Amanpulo's beachside, treetop and hillside villas all feature comfortable decks（木质平台）with hammocks（吊床）from which to enjoy the spectacular views of the greenish-blue sea below. Fill your schedule with Amanpulo's signature adventures (including diving, windsurfing and sailing), recharge in the award-winning spa or feast on locally caught seafood-the choice is yours.

    Song Saa, Cambodia

    Song Saa's incredible ocean views, and breathtaking sunsets are a very typical example of pure paradise. Its 24 villas—each with their own sea-view private plunge pool-are designed to reflect the natural beauty of Cambodia's coastline; built from recycled wood with straw roofs and driftwood furnishings, these presences are stylish proof of Song Saa's admirable commitment to sustainability and conservation. You can choose to do as much or as little as you want here. With rainforest tours, island safaris and reef snorkeling（徒手潜水）, it just offers some of the activities that show this spectacular destination.

    A British friend told me he couldn't understand why Chinese people love eating sunflower seeds as a snack so much. “I've met a lot of older Chinese and many have a crack in their front teeth; I believe that's from cracking the seeds, ” he said.

    I had never noticed the habit, but once he mentioned it, I suddenly became more aware. I realized that whenever I'm watching TV or typing a report, I always start mindlessly cracking sunflower seeds. My friend doesn't like sunflower seeds, and, to him, it seems unnecessary to work so much just to get one small seed.

    When we were young, the whole family would usually get together for Chinese New Year. Then, we all lived close to one another, usually in a small city, and sometimes even neighbors would go door-to-door on Chinese New Year's Eve to check out what every household was making.

    I remember my parents would be in the kitchen cooking. Out in the living room , a large table would already be laid out, complete with fancy tablecloth, ready-made dumpling fillings, and dishes full of candy, fruits and sunflower seeds. Some of the dishes were to be offered to our ancestors later, while others were for neighbors and children to eat before the evening feast. I must have learned how to crack sunflower seeds back then.

    I don't think it's right to criticize one's choice in food or eating habits, no matter how strange they may seem.

    It's not only in China. When I went abroad, I found people had all sorts of strange habits when it came to food. In Denmark, they put salted red fish on bread and eat it for dinner, no matter how much it ruins your breath. They think it's a delicacy, and it's connected to their culture. I think it's a wonderful tradition.

    A company has just launched what it calls “the world's first free standardized English test” recently. Anyone can take the test for free. The new exam is called the EFSET, which is short for Education First Standardized English Test. The company, Education First, is known by the letters EF.

    It is estimated that there are two billion English language learners worldwide. Many of them are interested in attending an American college or university. To do so, foreign students need to take the Test of English as a Foreign Language—better known as TOEFL. However, many foreigners are not wealthy enough to take the TOEFL. In addition, test-takers often have to travel overnight to reach an official testing site. The World Bank says an average Cambodian worker earns only about $1,000 per year. Approximately the cost of taking the TOEFL is 17.5 percent of the average worker's yearly wage.

    It is not just individuals who find the test pricey. Some governments also find it prohibitive. What's more, not everyone needs official results from the TOEFL or IELTS—the International English Language Testing System. In the future, it's likely that the government may use the EFSET to test millions of employees and students.

    Experts believe that the EFSET meets the highest value in language testing. It uses special computer software that makes the questions easier or harder, depending on one's performance. The EFSET measures all the English learners' levels while the IELTS and TOEFL only measure learners' levels from intermediate to advanced. The EFSET is unique in the sense that it gives free online access to anyone interested in measuring their English level.

    There is a 50-minute and a two-hour version of the test, which its developers are calling the EFSET Plus. Both versions test only reading and listening skills. It's hopeful that speaking and writing skills will be tested in the future. The IELTS and the TOEFL still use humans to rate the speaking and writing sections. It's a huge deal for students who are in areas where they can't get to the TOEFL or the IELTS. However, it is too early to know whether the EFSET results are acceptable for colleges and universities in America.

    Being an astronaut sounds cool, doesn't it? In space, they get to do some pretty amazing things, like floating (漂浮) in zero gravity(重力).

    However, there are also plenty of things that astronauts can't do because of their weightless environment(环境), and that's very sad. What's worse, they can't even let their sadness show -because it's impossible to cry in zero gravity.

    Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity；tears don't flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go — they just stick to your eyes.

    In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. "Tears," he said, "don't fall off your eye...They just kind of stay there."

    Besides making your vision(视觉) unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that's not the case in space. The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. "My right eye is painful like crazy." Feustel told his teammate during the walk.

    Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait — "When the tears get big enough they simply break free of the eye and float around," astronaut Ron Parise told The Atlantic.

    There are lots of small things — things like crying — that we are so used to on Earth, we usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (呕吐) everything in their stomach, according to the UK National Space Center.

    Thus, perhaps it's only space explorers who can honestly say, "Gravity, you're the best."

Andy Kong has worked very hard to get to where he is today. He credits becoming a millionaire by 20 to his strict Asian parents who tutored him at a young age by working for the family.

Kong, of Danville, Virginia, started working when he was only nine. English wasn't a strong suit for Andy's parents, and that's where he was able to assist his family the most. After school and on weekends he would help out at their family-owned restaurant and nail salons. Not only did he do the labor work, but he was also involved in creating online ads. This was his introduction to the world of online business.

Andy started his Amazon business in the eighth grade. When he learned about Amazon Dropshipping (代发货模式) from a kid he saw on Instagram, he got inspired and decided to give it a try. Unfortunately, the store eventually got shut down because he was impatient with the growth. Instead of considering it a failure, he viewed this experience as a life lesson and learned from his mistakes. Meanwhile, his parents never stopped trying to talk him into focusing on school and their retail business.

"The biggest challenge when starting a business is getting someone to believe in you," Andy says. He pushed through and did things for himself even when his loved ones discouraged it.

In 2019, Andy met his now business partners, and together, they created an Amazon management company called Project WiFi. This Project has proven to be extremely successful. They currently help over 55 clients run their online businesses, and plan to help many more in the future.

When asked about the secret to his success, Andy says, "Learning to sacrifice whether that's family, friends, or soccer game for a single goal is the only way to succeed, rather than attempting multiple things. If it's worth doing then it's worth doing well with no shortcuts."
