      Colonia friends are drawn to these aspects of Chinese culture:


      The Maijishan Grottoes, located in Tianshui City, Gansu Province, China, are a magnificent example of Chinese Buddhist art and architecture. The grottoes were first built during the Eastern Jin Dynasty (317-420 AD) and continued to be expanded and embellished over the course of hundreds of years, eventually becoming one of the largest grotto complexes in China. Today, the Maijishan Grottoes are a UNESCO World Heritage Site and a must-see destination for travelers interested in Chinese history and culture.

      The Maijishan Grottoes are carved into the side of a mountain, which rises dramatically above the surrounding landscape. Visitors must ascend a winding path up the mountain to reach the grottoes, which gives them a sense of awe and reverence before they even step foot inside. The majestic beauty of the mountain setting also serves to enhance the spiritual significance of the grottoes themselves.
      Inside the grottoes, visitors will find a treasure trove of Buddhist art and architecture. There are over 7,000 statues and more than 1,000 square meters of murals spread across 194 caves. The statues range from small, intricate carvings to large, imposing figures that span an entire room. Many of the statues are painted in vivid colors and adorned with gold leaf, creating a breathtaking visual display.
