83 The Condor Shooting is divided into three parts - Iron-Blooded Heart, Ashes of Time, and Huashan Swordsmanship. The corresponding theme songs are "Iron-Blooded Heart", "Life is Meaningful" and "The World Is Always Hello" . Could it be that the original poster is watching the 83 Condor Shooting broadcast on Anhui Satellite TV? What is playing now should be the first step of "Iron-Blooded Heart", then I remember that the ending song seems to be the pure music of "Iron-Blooded Heart".

You can search the three song titles I mentioned on Baidu MP3 to see if they are correct.
