      ZhongYuan takes Espo friends to see China! It is a journey that provides a deep understanding of Chinese culture and its enduring legacy.



      There are many historical and cultural heritages in China. I believe these cultural stories with a long history are attractive enough to make Espo friends interested in Chinese Built-in duck bill valve products.


      Cultural elements that must be comprehended when visiting China:

      Zhangjiajie is a natural wonder located in the Hunan Province of China, renowned for its steep sandstone pillars, deep canyons, and lush forests. It is a UNESCO World Heritage site and a popular destination for those who want to experience the beauty of nature and explore the rich history and culture of China.
      One of the most famous attractions in Zhangjiajie is the Zhangjiajie National Forest Park, a sprawling park that is home to thousands of towering sandstone pillars, some of which rise over 300 meters tall. These unique formations have been shaped by millions of years of erosion, creating a striking landscape that is unlike any other in the world.
      Another highlight of Zhangjiajie is the Tianmen Mountain National Forest Park, which features an impressive natural stone arch called Tianmen Cave. Visitors can ride a cable car through the valley to the cave, admiring the steep cliffs and lush forest below. They can then climb the stairs to the top of the cave for an unforgettable view of the surrounding landscape.
