1 . The best spring destinations in Tibet
The Qinghai-Tibet Plateau has long been an ideal and mysterious destination for visitors. Now with the arrival of spring, the climate is becoming more pleasant and Tibet has become an even better trowel destination. Here we recommend some of the best tourist destinations in Tibet which might suit your travel taste.
Peach blossom valley: Nyingchi
The peach blossoms in Nyingchi, Tibet Autonomous Region have been named as “the most beautiful peach flowers in the world”. A great time to visit Nyingchi for the peach blossoms would usually be from March 20 to Apil 15 each year.
The peach blossom valley in Bomi County, Nyingchi, stretches for 30 kilometers, making it one of the longest in China. Peach blossoms can be seen everywhere- around houses, across farmlands and along streams. Peach trees bloom depending on the altitude and climate, so visitors will have the chance to enjoy the blossoms throughout April.
The Yarlung Zangbo River Grand Canyon
The Yarlung Zangbo River Grand Canyon is the deepest canyon in the world. With a total length of about 500 kilometers, its altitude spans from 1,182 meters at Namchak Barwa, the highest peak of the eastern Himalayas, to 550 meters around the Yarlung Zangbo River Valley in Metog County.
One unique feature of the spring sight here is that visitors can enjoy both the peach blossoms and the snow-capped mountains at the same time.
Nanyi Valley
Nanyigou scenic spot is 20 kilometers away from Milin County and is an important birthplace of the mysterious Tibetan medicine culture. The scenic area rovers a total area of 820 hectares. The ecological conditions here are so good that the place is rich in various animal and plant species.
Surrounded by mountains and shrouded (遮蔽) in clouds, Nanyi Valley is an ideal spring destination for visitors, where you can find peach and azalea blossoms everywhere.

2 . Five Most Beautiful UNESCO World Heritage Sites in the USA
The UNESCO World Heritage Sites are some of the most beautiful places in the world. They represent a unique collection of landmarks, and the five parks in USA really deserve to be treated as such.
Yellowstone National Park, USA
The world’s first national park sits on top of a volcanic hot spot and offers everything from great views to fun activities and wildlife sightings. Home to lush forests, hot springs, alpine rivers, geyers, and more, it’s not hard to see why it’s one of the greatest parks in the USA.
Grand Canyon National Park, USA
Thanks to the erosion from the Colorado River, the Grand Canyon is among the best spectacles on the planet. Stretching almost 300 miles, this magnificent valley is almost a mile deep and the width varies between less than a half mile to almost 19 miles.
Yosemite National Park, USA
Yosemite’s glacial landform secures its spot among the best parks in the USA. This amazing park is also typically recognized because of its huge sequoias (红杉) and granite cliffs. In addition, you’ll find all sorts of picture-worthy meadows, waterfalls, streams, mountains, and a variety of plants and animals.
Carlsbad Caverns National Park, USA
A karst landscape defines Carlsbad Caverns National Park which houses more than 119 caves. Its two main standouts are the namesake Carlsbad Cavern and Lechuguilla Cave. Both are known for their natural beauty, reef formations, and geologic features, but Carlsbad Cavern is famous for having one of the largest limestone cave chambers in the country at 4,000 feet long while Lechuguilla Cave owes its fame to its rare speleothems, or secondary mineral deposits, that provide a natural laboratory to study biological and geological processes.
Hawaii Volcanoes National Park, USA
Home to two of the most active volcanoes in the world, Mauna Loa and Kilauea, Hawaii Volcanoes National Park was added to the UNESCO World Heritage List in 1987 in recognition of its outstanding natural values. The park is one of the biggest attractions in Hawaii as it offers visitors dramatic volcanic landscapes and glimpses of rare flora and fauna.

3 . Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.
