It was Kaho Hung's first trip to Germany, and of course Do Do had to take him deep into the depths of German culture - the Black Forest, to explore the precious natural and cultural resources of the largest forest mountain range in Germany. Starting from the famous Triborg Falls, Do Do and Kaho witnessed how the cherries in the forest are turned into wine, and then how the cherry wine is made into the world-famous Black Forest cake. When they finally tasted the authentic Black Forest cake in the Black Forest, Do Do and Kaho could taste the aura and history of this place with every bite.
