      ZhongYuan takes Coimbra friends 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 Coimbra friends interested in Chinese Rubber slow closing check valve products.


      If you have an interest in Chinese culture, let's take a look at it first.

      The Summer Palace is steeped in history and culture. It has been the site of numerous important events throughout Chinese history, including the signing of the Boxer Protocol and the negotiations for the founding of the People's Republic of China. The complex is also filled with statues, inscriptions, and other artifacts that testify to its rich cultural heritage and historical significance.
      Another highlight of the Summer Palace is its vast gardens, which cover nearly three quarters of the complex. The gardens are filled with winding paths, rock formations, and ancient trees, providing visitors with endless opportunities to meander and explore. Some of the most popular spots in the gardens include the Seventeen-Arch Bridge, the Suzhou Street, and the Long Corridor, a covered walkway decorated with more than 14,000 paintings.
      Perhaps the most charming aspect of the Summer Palace is its water features. In addition to Kunming Lake, the complex also contains a number of streams, waterfalls, and ponds, which are home to a variety of fish, turtles, and water birds. Visitors can take boat rides on the lake, watch traditional Chinese fishing techniques, or simply sit back and enjoy the tranquility of the water.
