I can't find the microphone, the sound in the video may be very poor 我找了很久都没有找到收音的麦克风，视频的声音可能会很差

I edited the video again, I recommend watching it with mute sound 我把视频重新剪辑了一遍，我建议静音观看~

声音调小，杂音会很大，虽然降噪处理了 Please turn down the volume. The noise will be very loud, although it has been reduced.

The video was not taken well, my bad 视频没拍好，我的错~
