Great wall of china

The Great Wall of China  stretches westward across the provinces and municipalities of Lioning, Hebei, Tianjin, Beijing, Inner mangolia, Autonomous Region, Shanxi, Shaanxi, and Ningxia  Autonomous Region to Ghansu in the west.

The Great Wall of China can be visited at many places along its length of several thousand kilometers. Its condition ranges from excellent to ruined, and ease of accessibility varies straightforward to quite difficult. Note that different sections also each have their own admission fees, e.g. if you want to hike from Jinshaling to Simatai then you probably have to pay twice.

The Great Wall, as we know it, is actually a series of several walls built at different times by different emperors. The categories below are non-exhaustive, and all refer to wall systems rather than single monolithic walls.

• First Great wall - built by the Qin Dynasty 221-207 BC
• Second Great Wall - built by the Han Dynasty 205-127 BC
• Third Great Wall - built by the Jin Dynasty 1200 AD
• Fourth Great Wall - built by the Ming Dynasty 1367-1644 

  Flora and fauna:

  Chinese wildlife is diverse, considering all of the different habitats available along the length of the Great Wall. From the rare Siberian tiger in the northeast to the protected and rare Giant Panda which lives in southern Gansu, Sichuan, and Shaanxi, you never know what you might see on a given day.
  Wild mammals can be found in the north, such as the Manchurian weasel, brown and black bears, northern pika, and mandarin vole. Deer species include Sitka deer, roe deer and the long-sought-after spotted deer, which has many uses in Chinese medicine.
  The birds of the region include various pheasants, black grouse, pine grosbeak, various woodpeckers, mandarin duck, and the fairy pitta, a rare migratory bird. Cranes are especially revered in China. Common, demoiselle, white-napes, hooded, and red-crowned cranes all breed in China. 
  You can find many tonic plants along the Great Wall, such as the rare ginseng (Panax ginseng). Chinese medicine has had many thousands of years to discover and use these tonic plants for the benefit of mankind.  In recent years, the public has expressed great concern about the protection and control of the wall. However, owing to its remote location, huge scale and complex structures, the protection work involves enormous difficulties. At present, policies and measures implemented are as follows: 
  
  A. Regulation on Great Wall Protection was specially issued by the State Council on September 20, 2006, and was enforced on December 2 of the same year. It consists of 31 articles, clearly stipulating the rights and obligations of the public and government, some prohibitions for the local people and visitors, rules for relative administration, as well as some punitive measures.
  B. Carrying out various propaganda work to let society know about the importance of the wall through media such as broadcasting, newspapers, cinema and TV.
  C. Making on-the-spot investigations to obtain accurate and detailed information so as to devise relevant measures.
  D. Improving the surrounding environment, especially in remote grassland and desert areas, by increasing reforestation.
