ZhongYuan takes you to see China! Quickly transitioning from a populous country to an industrial powerhouse, this is a magical country! There are many historical and cultural heritages in China. I believe these cultural stories with a long history are attractive enough to make friends interested in Chinese civil air defense two flanks protection closed casing pipe products. If you have an interest in Chinese culture, let's take a look at it first. The Mausoleum of the First Qin Emperor, also known as the Qin Shi Huang Mausoleum, is a historic site located in Lintong District, Xi’an, China. It is the final resting place of Qin Shi Huang, who was the first emperor of China and the founder of the Qin Dynasty. The mausoleum complex covers an area of over 56 square kilometers and is surrounded by several smaller tombs, pits, and burial sites. The main tomb is located at the center of the complex and is comprised of a pyramid-like structure that rises over 50 meters high. The tomb was constructed during Qin Shi Huang's reign and took nearly 40 years to complete. The tomb is surrounded by a moat and an outer wall that is over 1.5 kilometers long, with four gates that guard the entrance to the tomb. The tomb is also guarded by an army of life-sized terracotta soldiers, horses, and chariots that are positioned facing eastward, ready to protect the emperor in the afterlife.

Hello, friends.No matter where you are, we have a solution for you.

ZhongYuan respect your privacy. We will not proactively communicate with you anything beyond your wishes!
