The Qin Yuefu bell is cast in bronze, with a nose button, 13.3 cm high, 7.2 cm between the two mills, 5.8 cm between the drums, and 6 cm × 4.8 cm for the dance. Although buried in the ground for more than 2,000 years, the gold and silver patterns on the bell body are clear and complete after unearthed, showing a luxurious and elegant demeanor. The zheng part and drum part of the bell are inlaid with gold pan patterns, the seals and the bell belt are inlaid with gold flowing cloud patterns, and the bell belt is inlaid with silver flowing cloud patterns.

There are also hair-thin moiré patterns on the inside of the bell. The inner walls of the bells we have found in the past are plain and do not have decorative patterns, but the inner wall of this Yuefu bell is engraved with cloud patterns, which is extremely rare in archaeology. So how is such a beautiful decoration made? The Qin Yuefu bell adopts the inlaid and wrong combination process, that is, the cast bell body is inlaid with gold and silver wire into a pattern, and then the surface of the bell is polished to make the pattern clear and the lines clear.
Casting such a slender pattern, one is that it is not easy to make a mold, and the other is that it is difficult to control the temperature of the copper bucket during casting. If the temperature is too high, the horizontal lines will easily be washed away. If the temperature is too low, the copper bucket will not flow smoothly, and the pattern will be incomplete. The pattern of this clock is basically complete and clear, which is amazing. It fully shows the superb bronze smelting level and craftsmanship of the Qin Dynasty, and provides precious physical data for further research on ancient gold and silver and inlay craftsmanship.
Qin Yuefu bell is not only beautiful, but also contains a wealth of music theory knowledge as an ancient musical instrument. There are four tuning tapes on the inner wall of the bell, and there are file marks, indicating that the Qin people have tuned the bell. In 1982, Mr. Lu Ji, a famous musician, rang the Yuefu Bell for the first time in 2,000 years, and identified it as the key of C. The sound quality was crisp and pleasant, and the pitch was high. This is undoubtedly of great significance in understanding and discussing the musical achievements of the Qin Dynasty.
