Can anyone help me identify this tea?

I got a sample from a friend (I don’t have their contact unfortunately) and they told me this was a “Dahn Mi Ling?” I don’t know if I heard right, it’s a pretty rare Chinese mountain oolong he told me, it tastes so dewy and clear like a breezy blue summer night on a grassy knoll. I really don’t have more information. (Please no one say iron goddess/tiguanyin/etc. I’m sure it’s not, I asked him and he said something that sounded like “Dahn mi ling” again… I’m a little hard of hearing lol)
