If you play music, it is also recommended to use olive trees. If you can't find the light music version, you can play the original singing version. But the last paragraph needs an enhanced cadenza, which can be used as a prelude to the Yellow River Chorus or "Towards Rejuvenation" or "Singing the Motherland". The volume of this cadenza should be increased at the end of the recitation, and it should continue to be played at a high volume for a period of time after the text recitation.
