The chin looks like an earthenware bowl and is placed in the old monk's room. The old monk burns incense and recites scriptures every morning and evening, and always knocks his chin with a hammer.
Qing issued a "when! When ... "Clear voice. But I don't know why, sometimes, Lao He doesn't knock yet, and it rings for no reason. The monks in the temple thought there was something evil, and invited many people who knew magic to subdue evil, but to no avail. The old monk was so suspicious that he was afraid of falling ill.
The old monk has a friend named Cao Shaokui. He heard that the old monk was very ill, so he went to visit him in the temple and asked him the reason for his illness. The old monk told him in detail the strange things that he made noise. Cao Shaokui knows a lot about music and can repair various musical instruments. He listened and thought. He thought, this chime is making trouble by himself, and it is definitely not an evil spirit. There are always some reasons. It's just time for dinner. The young monk went to the bell tower to ring the big clock. The chin in the old monk's room rang again Cao Shaokui fully understood in his heart. He smiled and said to the old monk, "Please treat me to a good meal tomorrow, and I will exonerate you." Csi still don't believe that Cao Shaokui can really get rid of strange things, but seeing that he is so sure, there may be a glimmer of hope, so he really hosted a sumptuous dinner and invited Cao Shaokui. After eating, Cao Shaokui took out a document from his arms and filed it here, there and there several times. He said to the old monk, "Don't worry, the bell will never ring by itself again."
From then on, Qing Zhen stopped ringing by herself. The old monk asked Cao Shaokui, "Why did it stop ringing after you filed for a few minutes?" Cao Shaokui replied, "The rule of this chime is exactly the same as that of the big clock in your bell tower. So as long as the big clock in the dining hall rings, the chime will ring with it. I filed my chin several times, but their rules were different. So when I rang the big clock, the bell stopped ringing. " Hearing this, the old monk dispelled his doubts and recovered his health. Cao Shaokui's "method" refers to the "frequency" of musical instruments now. What is "frequency"? Is the number of vibrations per second when the instrument makes a sound. The chime in the old monk's room has the same frequency as the big clock in the dining hall. As soon as the young monk strikes the clock, it vibrates and emits sound waves of a certain frequency. Sound waves pass through the air and reach the chin in the old monk's room. Because the frequency of the chin is the same as that of sound waves, it vibrates and makes noise. This phenomenon is called "* * * vibration" or "* * * ringing" in physics. Cao Shaokui filed the chime a few times, and the frequency of the chime changed. The frequency of Qing is different from that of the big clock, and it won't ring with the big clock again.
