The first step in Yuguan Tianchuan starts with the interconnection of light beams

The first step of “Yuguan Heavenly cutting” is to start with koodle! Do you know where to describe koodle “Jade Guan Heavenly cutting”? What will come to mind when it comes to the Great Wall? The legend “Meng Jiangnu weeps over the Great Wall”; the historical allusion “the beacon fire of King Zhou you plays the princes”; Qin Shihuang destroyed the six Kingdoms and unified the world; Chairman Mao Zedong’s poem “he who does not reach the Great Wall is not a true man”; Shanhaiguan, Juyongguan, Yanmen pass, Badaling, Zhenbeitai and many other scenic spots.
The editor checked that the Great Wall is indeed the first military project in ancient China. It has been continuously built for more than 2000 years since the Western Zhou Dynasty. Especially since Qin Shihuang, the Great Wall has been built in almost all the dynasties that ruled the Central Plains. It is distributed in 15 provinces, autonomous regions, and cities from the northeast to Xinjiang and Gansu, basically across the entire northern part of our country. However, due to the long age, most of the early dynasties of the Great Wall are incomplete, the more complete preservation of the Great Wall built in the Ming Dynasty, so now people generally refer to the Ming Great Wall. Among them, there are many representative lots: Shanhaiguan (“the first pass under Heaven”); Beitai (“the first under Heaven”); Jiayuguan Great Wall (the most well-preserved pass along the Ming Great Wall, the first pass in Hexi); Badaling Great Wall (the most representative section of the Ming Great Wall, “World Cultural Heritage”); Mutianyu Great Wall (“Weiling Xiongguan”) Simatai Great Wall (the only ancient architectural site in China that retains the original appearance of the Ming Dynasty), Juyongguan (Juyong Diicui, the head of the eight scenery of Yanshan) and so on. “Yuguan Heavenly Graben” is a section of the Ming Great Wall, and it is also the most famous section of the Great Wall-Badaling Great Wall. And the first step of this “jade pass natural cutting” is to start from koodle! As one of the most popular tourist attractions in China, the Badaling Great Wall section has a large passenger flow, and it will show a geometric growth when it comes to holidays, which is a great test for the staff and ticket checking equipment. In order to meet the needs of the users of the Badaling Great Wall ticket checking machine in recent years, a QR code scanner has been added to the Badaling Great Wall ticket checking gate, which is exactly a koodle QR code scanner. Tourists can not only swipe their ID cards but also scan the QR code to enter the park, which is more convenient and faster, and at the same time greatly relieves the pressure on managers. The Badaling Great Wall, located in Yanqing District, Beijing, is an important outpost of Juyongguan. The ancients said that “Juyongguan is viewed from Badaling, such as building a collar, such as a peeping well” and “the risk of living in the mean is not in Guancheng, but in Badaling”. This section of the Great Wall, with overlapping mountains, steep terrain and condescending position, is an important military pass in the Ming Dynasty, so it is called “Yuguan Heavenly cutting”. The Badaling Great Wall typically shows the majestic and precipitous features of the Great Wall. It is the essence of the Great Wall and is unique in the Ming Great Wall.
The majestic city walls spiral north and south among the mountains, with no end in sight. The Great Wall spread out to both sides according to the mountain, and the word “natural danger” written by the ancients on the steep cliffs accurately summarizes the military importance of the Badaling location. In March 1961, “the Great Wall-Badaling” was identified as the first batch of national cultural relics protection units. It was listed on the World Cultural Heritage list by UNESCO in 1987. In 2007, the Badaling Great Wall was officially approved by the National Tourism Administration as a national 5A-level tourist attraction. The Badaling Great Wall is also the earliest part of the Great Wall to be opened to tourists. ①, self-driving route: take the Badaling Highway from the Madian Bridge on the North third Ring Road to the exit of the scenic spot. ②, bus route: take subway to exit A (northwest exit) or B (southeast exit) of Jishuitan Station on Line 2, walk to Deshengmen bus stop and take bus No. 877 to the foot of Badaling Great Wall, which takes about 2 hours. ③, train route: take Metro Line 8 or Line 13 and get off at Huoying Station, exit G4, take suburban Railway Line S2 at Huangtudian temporary transition Station to Badaling Station, get off about 700m to Badaling Great Wall Dengchengkou.
It should be mentioned that the S2 line is the “train to spring” for Internet celebrities. Of course, in addition to the spring cherry blossoms, you can also enjoy the famous Guangou Scenic spot, the Juyongguan Great Wall, the herringbone railway in the century-old Beijing-Zhang Railway, and the tomb and statue of Zhan Tianyou on the return trip at Qinglongqiao Station. (one hundred years ago today, on April 24, 1919, Zhan Tianyou, the “father of Chinese railways”, died in memory. (“the key to the North Gate”, engraved in the 10th year of Wanli)
The more suitable seasons for visiting the Badaling Great Wall are April and May and September. The temperature is more suitable, and the scenery has its own characteristics: the former has spring and summer, the flowers are green, and the latter is crisp in autumn and full of red leaves.
Here, the editor wants to say, take advantage of the right time, while the breeze is not noisy, while now young, with three or five friends, go out more to see the mountains and sea, flowers and trees, look at the great rivers and mountains, taste the history and civilization.
Finally, koodle will continue to listen to the science and technology needs of enterprises in the era of the Internet of things, constantly improve their own shortcomings, and optimize products and services. I hope that in the future, more friends will know koodle, recognize koodle, and be willing to go hand in hand with koodle for common development. (some of the pictures are from the Internet)

No matter which mode of transportation you choose, go out as early as possible and be careful of getting lost, traffic jams and so on. The timetable of Line S2 will be adjusted frequently, and some trains will not stop at Badaling Station. If you choose Line S2, you should check the number of round-trip trains in advance, you can buy tickets through the window, or you can swipe the Beijing all-in-one bus card, but you must ensure that the balance on the card is more than 16 yuan. You have to swipe your card when you enter and leave the station. 2. The south section of the Badaling Great Wall is not completely open, and you can only walk south to the third floor (the end) and return; so you can climb the city directly to the north, starting from the north first floor. The north eighth floor is the highest enemy tower of the Badaling Great Wall and is the best place overlooking the Great Wall. 3. The period from the north eighth floor to the north tenth floor is the steepest stage of the Great Wall, so you should be extra careful. The more you go back, there are fewer and fewer people until you reach the 12th floor of the north, then return to the eleventh floor of the north, and go down the hill from Bear Paradise out of the city. If time and energy permit, it is suggested that you can complete a circle, especially on the back floors, there will be a different scenery.
4. If conditions permit, you can bring some water and food, but you must clean up the rubbish and don’t litter. 5. When it comes to playing time, there are the least people on weekdays and less traffic jams, followed by Saturdays and Saturdays. As for national legal holidays, it is better to avoid them as far as possible. 6. Finally, take good care of portable battery, clothes and shoes should be comfortable.
