The Great Wall is the most famous of the world's cultural heritage in China. The history of the Great Wall can be traced back to the Western Zhou Dynasty. The famous allusion of the capital, Xijing (now Xi'an, Shaanxi), originated from this. During the Spring and Autumn Period and the Warring States Period, the countries competed for hegemony and defended each other. The Great Wall built the first climax, but the length of construction was relatively short. After the Qin and the Six Kingdoms unified the world, Qin Shihuang connected and repaired the Great Wall of the Warring States, and was known as the Great Wall. The Ming Dynasty was the last dynasty to overhaul the Great Wall. Today, many of the Great Walls that people saw were built at this time. The most well-known in Beijing is the Badaling Great Wall. The traffic is very convenient, but it is often overcrowded. Although the Great Wall of Mutianyu near Juyongguan does not have the great Badaling in the name, but because the form is particularly beautiful, the shape of the Great Wall is well preserved and it is worth recommending, and generally there is no one after 4 pm, you can finish it here. The photo of the Great Wall is very atmospheric.
