Well let me elaborate a bit more......

We can not let other people visit our own computers (like C driver)

We can only share it in a public reservoir though uploading

Then, you'll get a link sent directly to your QQH shows the solid address of your ".mp3" file

After that, you can copy the link to "媒体位置" under "real media"

Click on "Cha Ru", done! ^v^
