Ancient Observatory (Guguanxiangtai)

20230211 I decided to come to the ancient observation deck temporarily. At present, the public account can be made on the same day. The ancient observation deck is located in the second ring road, the southwest corner of Jianguomen Overpass (Dongcheng District Dongguan Hutong No. 2), built during the orthodox period of the Ming Dynasty (1442 AD), is one of the oldest observatories in the world, and is also the Royal Observatory of the Ming and Qing generations in China. It is famous for its complete architecture, complete equipment and long history. In fact, there is no understanding of these knowledge of astronomy, that is, looking at the wisdom of these ancients hundreds of years ago, it is also a kind of enjoyment. Learn about the different work of Chinese and foreign cultures, understand the loss and return of cultural relics, and improve your thinking.

Beijing Ancient Observation Deck, there are two indoor exhibition halls, you can learn a lot of astronomical knowledge. For example, the moon has a striking round gap change. From the beginning, the moon phase has gradually increased from no to the picture, and then gradually lost to no. The ancients called this the moon's profit and loss phenomenon. The expected moon is a period of profit and loss of the moon phase. The moon constantly undergoes changes in the phase cycle from the look back to the new moon. Astronomers define the interval between the phases from the look to the new moon (or from the look to the look) as the expected moon. The average length of a new moon is 29.53 days, that is, 29 days.

Beijing Ancient Observation Deck was built in the seven years of Ming Orthodox (1442), is a national observatory of the Ming and Qing dynasties, and is also one of the oldest observatories in the world. The ancient observation deck is about 14 meters high, the top of the north and south is20.4 meters long, and the east and west are23.9 meters long. There are 8 Qing-made astronomical instruments on it. From the beginning of Ming orthodoxy to 1929, the ancient observation platform engaged in astronomical observation for nearly 500 years, is the world's existing ancient observatory to maintain the longest continuous observation observatory, plus the complete equipment, platform and annex building complete, so it has been famous internationally. In addition to the shape, flower decoration, craftsmanship and other aspects of the Chinese tradition, in the scale, travel watch, structure and other aspects, it also reflects the progress and achievements of large astronomical instruments after the Renaissance era in Western Europe, so it has become an important historical witness to cultural exchanges between China and the West. The Beijing Ancient Observation Deck was listed as a key cultural relics protection unit in the country in 1982.

On the weekend, a person came out to visit the Ancient Observatory beside Jianguomen. The first time I came here was probably because of the holidays. Many parents took their children to visit the observatory. The observation instruments here were all made in Kangxi period of the Qing Dynasty. Today, they have a history of several hundred years. There are seven instruments on the observatory. They are all carved dragons and phoenixes, ancient fragrance and ancient color. Although they are all introduced, they can't understand what they are doing. They have to admire the wisdom of the ancient people. In the era of science and technology and underdevelopment, they can design these precision instruments. There are three exhibition halls under the observatory, which show some scientific and technological achievements of ancient China. If you have children, it's good to take them with you. You can learn a lot of knowledge that you don't have in the textbooks.

Years ago, when I walked through the second ring road, I always saw some ancient instruments on the city floor. I was always curious about where this is. Later, I was always concerned. I finally looked forward to the opening visit. After a few trips, today I specially brought my lady to understand the ancient astronomy. Historical knowledge, look at ancient Chinese achievements in astronomy. This place is not far from the bus and subway. You can buy tickets online in advance. Adults 20 and minors are free, but you also need to make an appointment. If you change the ticket, you will have a brochure to learn some basic knowledge. The ancient observation platform of China was built in the early Ming Dynasty, earlier than the famous ancient observatories abroad, and worked until 1929, observing for more than 500 years, is the world's longest observation activity observatory, fully proving the ingenuity of the ancient Chinese. Today, China has achieved higher achievements in various scientific and technological fields, such as China's "eye of heaven" is also a top product in the world's astronomy field. The visit here is divided into three parts, first a courtyard house, the rooms in the east, west and north are exhibition halls, which introduce the history of the ancient observation deck, the comparison with other ancient observatories in the world, and the astronomical instruments invented in ancient China. Ancient Chinese astronomers and so on, the yard is a model of some ancient instruments; the small courtyard is a rectangular garden, the garden displays some ancient astronomical instruments of the real thing; To the north of the small courtyard is the city building of the observation deck. When you climb up the city, you can see the ancient astronomical instruments displayed on the city floor. These instruments can be said to be a lot of fate. During the invasion of China, the eight-country coalition forces were robbed and displayed in their own countries. It was not until after World War I that China returned to China because of its victorious status, which can be said to have done a good job in the astronomical cause of ancient China, and suffered shame because of the decline of the Qing Empire. Fortunately, they have now returned to the arms of their motherland and returned to the ancient observation decks that they once worked. Today, I also saw a staff with a group of children to carry out theme activities. This is very good. Children should participate in this activity from an early age and cultivate interest in science. In addition, the observation deck is located in the second ring road of Beijing, on Chang'an Street, it can be said that it is a relatively central location in Beijing. Standing on the upper floor of the observation deck, you can see the most prosperous section of Chang'an Street and the East Second Ring Road. You can also overlook the CBD high-rise buildings in the northeast direction. The scenery is also very good.

Beijing Ancient Observatory was built in the orthodox years of the Ming Dynasty, and has a history of more than 500 years. It belongs to one of the earliest observatories in the world. Both Ming and Qing generations have carried out a lot of construction and maintenance, and built many very advanced astronomical and observation instruments at that time. The integrity of the instrument package is also leading in the world, and astronomical observations were carried out until the Republic of China. Tickets for the visit are 20 and need to be purchased at the on-site ticket office. The area included a small courtyard, a garden with astronomy instruments, and the observation deck tower. The courtyard had three exhibition halls, which showed the development of the observation deck and the principles of some astronomical instruments, as well as the knowledge of world famous observatories and astronomers. The ancient instruments displayed on the upper floors of the garden and the observation deck reflect the development of ancient Chinese technology and the wisdom of ancient people, which is still very shocking. In addition, through the exhibition, we also learned the history of the insult of modern China by imperialist bullying. The instruments of the observation deck were robbed by the aggressors as trophies. I have lived in Beijing for 40 years, and I didn't come to the observation deck to see it before. Today I finally came!
