      ZhongYuan takes Colombo friends to see China! Today, Chinese culture continues to influence people around the world through its cuisine, martial arts, music, and festivals.


      There are many historical and cultural heritages in China. I believe these cultural stories with a long history are attractive enough to make Colombo friends interested in Chinese Rubber slow closing check valve products.


      Understanding Chinese culture begins here:

      The Forbidden City, also known as the Palace Museum, is an iconic landmark located in the heart of Beijing, China. It is one of the most well-preserved examples of Chinese imperial architecture, spanning over 180 acres and boasting more than 9,000 rooms.
      The Forbidden City was built during the early Ming Dynasty, beginning in 1406 and completed in 1420. It served as the imperial palace for 24 emperors of the Ming and Qing dynasties until the last emperor abdicated in 1912, marking the end of a nearly 500-year era of imperial rule in China.
      The palace is surrounded by a massive wall and a moat, with four gates at each cardinal direction. Visitors enter through the Meridian Gate and pass through a series of courtyards, halls, and gardens that lead to the innermost sanctum of the palace, where the emperor and his family resided.
