Lying at the city center and called Gu Gong in Chinese, it was the imperial palace for twenty-four emperors during the Ming and Qing dynasties. It was first built throughout 14 years during the reign of Emperor Chengzu in the Ming Dynasty (1368-1644). Ancient Chinese Astronomers believed that the Purple Star (Polaris) was in the center of heaven and the Heavenly Emperor lived in the Purple Palace. The Palace for the emperor on earth was so called the Purple City. It was forbidden to enter without special permission of the emperor. Hence its name “The Purple Forbidden City”, usually “The Forbidden City”.

Now known as the Palace Museum, it is to the north of Tiananmen Square. Rectangular in shape, it is the world's largest palace complex and covers 74 hectares. Surrounded by a 52-meter-wide moat and a 10-meter-high wall are more than 8,700 rooms. The wall has a gate on each side. Opposite the Tiananmen Gate, to the north is the Gate of Divine Might (Shenwumen), which faces Jingshan Park. The distance between these two gates is 960 meters, while the distance between the east and west gates is 750 meters. There are unique and delicately structured towers on each of the four corners of the curtain wall. These afford views over both the palace and the city outside.

It is divided into two parts. The southern section, or the Outer Court was where the emperor exercised his supreme power over the nation. The northern section, or the Inner Court was where he lived with his royal family. Until 1924 when the last emperor of China was driven from the Inner Court, fourteen emperors of the Ming dynasty and ten emperors of the Qing dynasty had reigned here. Having been the imperial palace for some five centuries, it houses numerous rare treasures and curiosities. Listed by UNESCO as a World Cultural Heritage Site in 1987, the Palace Museum is now one of the most popular tourist attractions world-wide.

Construction of the palace complex began in 1407, the 5th year of the Yongle reign of the third emperor (Emperor Chengzu, Zhu Di) of the Ming dynasty. It was completed fourteen years later in 1420, and then the capital city was moved from Nanjing to Beijing the next year. It was said that a million workers including one hundred thousand artisans were driven into the long-term hard labor. Stone needed was quarried from Fangshan District. It was said a well was dug every fifty meters along the road in order to pour water onto the road in winter to slide huge stones on ice into the city. Huge amounts of timber and other materials were carried from faraway provinces.

Ancient Chinese people displayed their very considerable skills in building it. Take the grand red city wall for example. It has an 8.6 meters wide base reducing to 6.66 meters wide at the top. The angular shape of the wall totally frustrates attempts to climb it. The bricks were made from white lime and glutinous rice while the cement is made from glutinous rice and egg whites. These incredible materials make the wall extraordinarily strong.

Since yellow is the symbol of the royal family, it is the dominant color in it. Roofs are built with yellow glazed tiles; decorations in the palace are painted yellow; even the bricks on the ground are made yellow by a special process. However, there is one exception. Wenyuange, the royal library, has a black roof. The reason is that it was believed black represented water then and could put out fire.

【推荐2】The Lake of Heaven

Changbaishan is in Jilin Province, Northeast China. Much of this beautiful, mountainous area is thick forest. Changbaishan is China’s largest nature reserve and it is kept in its natural state for the people of China and visitors from all over the world to enjoy. The land varies in height from 700 meters above sea level to over 2,000 meters and is home to a great diversity of rare plants and animals, Among the rare animals are cranes, black bears, leopards and tigers. Many people come to Changbaishan to study its unique plants and animals. Others come to walk in the mountains, to see the spectacular waterfalls or to bathe in the hot water pools. However, the attraction that arouses the greatest appreciation in the reserve is Tianchi or the Lake of Heaven.

Tianchi is a deep lake that has formed in the crater of a dead volcano on top of the mountain. The lake is 2,194 meters above sea level, and more than 200 meters deep. In winter the surface freezes over. It takes about an hour to climb from the end of the road to the top of the mountain. When you arrive you are rewarded not only with the sight of its clear waters, but also by the view of the other sixteen mountain peaks that surround Tianchi.

There are many stories told about Tianchi. The most well-known concerns three young women from heaven. They were bathing in Tianchi when a bird flew above them and dropped a small fruit onto the dress of the youngest girl. When she picked up the fruit to smell it, it flew into her mouth. Having swallowed the fruit, the girl became pregnant and later gave birth to a handsome boy. It is said that this boy, who had a great gift for languages and persuasion, is the father of the Manchu people.

If you are lucky enough to visit the Lake of Heaven with your loved one, don’t forget to drop a coin into the clear blue water to guarantee your love will be as deep and lasting as the lake itself.

【推荐1】One New Year’s Day, ecologist Rob Wolton came up with an unusual resolution—to spend the next 12 months studying a hedge(树篱) 40 metres from his house in the middle of Devon. He wanted to make a list of every plant, animal and fungus(真菌)that used it. After a year of observations he had found 2, 000 species—far more than he imagined. Wolton says he enjoyed it hugely and his findings contribute to the growing body of evidence that hedges should not be overlooked.

“There is increasing recognition that much of the wildlife finds shelter in the hedges. But they’re much more than just wildlife passages—they are really important as habitats in their own right,” he says. The European commission’s Joint Research Centre recently argued that as the climate crisis worsens, hedges are expected to play more roles as they move in response to environmental change. Their deep roots help sequester carbon(固碳), and they also reduce the likelihood of flooding downstream, suck nutrients and pollutants out of water, and prevent soil loss. Alongside these functions, there is a cultural benefit to hedges too—I think lots of us who live in England think of the hedge landscape as being quite typical, says Wolton.

After the Second World War many hedges were removed to create more productive land. Only about one in three hedges in England are in good condition, according to the most recent research done in 2017.

The main issues are hedges being cut too severely and too frequently, which leads to loss of wildlife and gaps. A squirrel, for example, will turnaround if there is a gap of five metres. New hedges are being planted with single species, instead of many, which decrease the wildlife they can support.

It’s hard to say if interest in hedges will translate into action on a national scale，and much depends on what landscape features Environmental Land Management scheme.

【推荐2】For sharks, the Mesoamerican Reef, which stretches over 600 miles, is a busy highway. Sharks use it to find their way and it provides them with food and habitat.

But as with on-land highways, this superhighway can be dangerous. Overfishing, commercial development and illegal practices are endangering the species. “We’re seeing a continued decline in shark populations. Our goal is to turn that round.” says Rachel Graham, founder of Mar Alliance, a non-profit organization focused on conserving sharks.

By monitoring sharks, Mar Alliance can collect important knowledge on the species to help inform conservation and push for political action. But rather than acting in opposition to the local fishing community, MarAlliance enlists their help.

“They are the ones who are on the sea every single day,” says Graham, “and they’re the ones who decide the species’ future.”

MarAlliance employs up to 60 fishermen across its range, mostly on a project basis, training them to collect data, record and release fish. Not only does this provide an alternative income to fishing communities, making them less dependent on natural resources, but it also teaches them about the benefits of a healthy ocean ecosystem and how to fish sustainably.

Among them, Ivan Torres, who used to catch sharks to sell locally as food, has learned how critical they’re to the whole ecosystem, saying he’d never fish sharks any more.

If this attitude change continues to spread throughout fishing communities, Graham has hope for the shark populations. “The primary threat to sharks is unquestionably overfishing,” she says, “By reforming the industry, populations can bounce back.”

In 2020, Belize outlawed the use of gillnets, large panels of netting of trapping large sealife. The ban’s impact is already noticeable with a recorded 10-fold increase in shark populations.

But such regulations need to be copied along the whole superhighway for long-lasting impact, and countries need to find a sustainable balance between fishers and the fished. “We need to find a win-win strategy between fisher livelihoods and shark survival,” Graham emphasizes. “I hope that through education and providing an economic alternative for fishing communities, MarAlliance will help ensure safe passage for sharks along the reef”.
