需要将音乐文件bhk_med.wav放于D盘根目录下才可以直接执行程序，或将程序中的音乐文件路径指向当前目的音乐所在的地址。背景音乐可以更换，甚至可以自行合成。(Music files need to be put in the D bhk_med.wav root directory before you can run the program directly, or to program the music file path to the address of the current purpose of music is located. Background music can be replaced, even on their own can be synthesized.)
