If you encounter this situation, you can only replace it with the bow of the player next to you, or you can use your own spare bow if you have one. When we perform on important occasions, we are often very nervous inside. The slightest disharmony will cause us to panic, resulting in an imperfect performance. While Gao Shen was playing, the strings broke. This was undoubtedly a fatal problem, but he did not waste any time thinking about it. Instead, he smiled, changed the piano with "thunder speed", and continued Play. This tells us that although a perfect performance requires careful preparation over many years, when sudden problems occur, we still need to learn to be adaptable and fearless in the face of danger. Of course, it is better to be prepared and have a response strategy in advance.
