Quality of the Zither

At this point, Zhou Linghuai smiled. "Later, I happened to find a type of spider silk. This spider was created near the copper mine. The silk is as thin as a woman's hair strand. It's difficult to see with the naked eye. It's slightly reddish-yellow and extremely tenacious. Moreover, it's not easy to break. It's twisted into a silk string. Its sound is clear and distant, and it sounds like gold and jade. It's very natural."

Just making silk strings was very difficult.

More than 300 threads of spider silk of the same thickness were twisted into strings. The best strings had to be even and natural. It was impossible to tell with the naked eye that many of them were twisted together.

After forming the string, the silk string had to be firm and smooth.

It was tough and not easy to break. The sound lasted even longer. It felt slippery, was easy to play, and its sound was purer. It did not hurt one's hands, and its sound was more round and clear.
