Female voice: Amy Diamond’s heartbeat, Feng Xiyu’s songs are also very nice, with a light and fresh style, such as I had a cold in that corner, flow. For pure music, I recommend these: The Promise from The Secret Garden and some pure music from "The Secret That Cannot Be Telln", "Emerald" from "Emerald on the Roof" such as Father and Son, which is a piano and violin ensemble , very nice, and also the famous "Kiss the Rain".
