I want to listen to ancient poetry recitation, such as pipa. How can I download it to my mobile phone?

Don't bother. I suggest you collect "audio books" and "my ancient poetry book" of Tang poetry and Song poetry on your mobile phone. There will be a very good version, but you need to find a place with WIFI signal to download it to your mobile phone, otherwise your traffic will exceed the standard ~ ~

I use the version on the blue page, which contains: introduction, translation, appreciation, design, which is quite convenient.
