Semi-black white is Mandarin Duck in Tea Hong. I am still not certain whether this is a good trade name for the tea.
@raphael, Fuding is great place to visit, but trying to find the right producers there is a bit of a hunting game. Production locations are not simple sidetracks on normal tourist routes. More so if you are a laowai. You have better luck in those tea markets in Fuzhou where you can sample many different qualities in a day. Update us of your finds!
