All the software of ihpone can't add local files stored in the mobile phone, but you can use WIFI to transfer songs from the computer to the mobile phone. How to use: First of all, the mobile phone and the computer must be under the same WIFI. After turning on WIFI to transmit songs in the software settings, a URL appears. Enter the web address on the computer and you can add songs. Other music software (such as listening to songs every day) and e-book software have this function. I have never used "Xiaoying", but you can find out whether there is "WIFI to songs/files" in the settings. I hope this humble opinion will help you.
