Founded in the Spring and Autumn Period, completed in the Warring States period of Qi Great Wall, west of the Yellow River, east to the Yellow Sea, 13 counties in Shandong, for more than a thousand miles. Qi Great Wall is also a place where the relics of the Great Wall built by countries during the Spring and Autumn Warring States Period are more protected. It is built in the mountains of the undulating Taihe Mountains. Although there are Pinggu places along the line, it is mostly mountainous and the Great Wall is built on the mountain. Its buildings are magnificent and spectacular in scale, condensing the hard work and wisdom of our working people 2,500 years ago, and also reflects the strong and powerful style of the East of the first hegemon and the seven males of the Warring States. In December 2012, the "Qi Great Wall Cultural Belt" has been identified as one of the main goals and tasks during the "Twelfth Five-Year Plan" period in Shandong Province.
