The world-famous Zenghouyi chime bells were unearthed in Suizhou, Hubei. Suizhou currently has 19 sets of bronze chime bells from various historical periods, totaling more than 400 pieces. They are world-renowned for their early age, largest number, heaviest volume, widest range of sound, and highest value, and are known as the "Hometown of Chinese Chime Bells". The bronze chime bell making technique is a traditional "ceramic mold casting technique" that has been passed down in my country for thousands of years. It is a process of pouring scientifically proportioned copper, lead, and tin bronze molten metal into a pre-made ceramic chime bell mold, and then cleaning, polishing, and tuning it after cooling and solidification to make it a bronze chime bell. Suizhou's bronze chime bell making technique began in the Shang and Zhou dynasties, and has been passed down through family and folk master-apprentice methods to this day. It uses copper, tin, and lead as materials, and goes through dozens of processes such as mold making, mold making, crusting, casting, trimming, and tuning to make more than two bronze bells, which can be grouped and hung for performance. Its technical features are the unique tuning technique of "one bell with two tones", the scientific ratio and dosage of "alloy raw materials" and the superb "lost wax method" casting process. The chimes made are beautifully shaped, exquisitely decorated and precise in pitch. They are the first of the "eight tones" of ancient musical instruments, more than 2,000 years earlier than the European twelve-tone equal-tempered piano, and have rewritten the history of world music. Xiang Shaoqing of Suizhou Zenghouyi Chime Culture Co., Ltd.'s "Bronze Chime Making Technique" combines craftsmanship, music, and rituals, and can reproduce the glory of the ritual and music culture more than 2,000 years ago. On May 24, 2021, the bronze ware making technique (bronze chime making technique) applied by Zengdu District, Suizhou City, Hubei Province was approved by the State Council to be included in the fifth batch of national intangible cultural heritage representative projects.
