"Dahua History of Chinese Art" gives people a whole new understanding of the treasure of bronzes, Zeng Houyi's chimes. Using "amazing" to describe the ancestors felt pale.

1. In the casting process, the ratio of copper, tin and lead should be strictly controlled. (The amount of tin is 13%--16%, and the amount of lead is 1.2%--3%)

2. One bell with two tones, this is the unique craft of chimes in the pre-Qin period in China. (The tile-shaped design, the tunnel is dug in the bell body for sound insulation. The error of the front drum sound and the side drum sound is within the range of 5 cents. Up to now, there is no better way. It can only be slowly polished on the bell wall by hand.)

The wrong gold inscription of 3.3775 characters engraves the important information of the pre-Qin music. (Anyone who sees the different names of the same sound in different vassal states will know how to play it.)

4. Many experts in my country's archaeology, music, machinery and other fields worked together to study the replica "Zeng Houyi Chime", which also cost millions, and it took 5 years to finally succeed.
