In the middle of Berlin-Weißensee, in a side street with the beautiful name Langhansstraße, there is a magical place. You enter through a gate into a wide courtyard, at the end of which stands an old factory building with yellow bricks and red-edged windows. Climbing up to the second floor, you enter a spacious room reminiscent of a teahouse. The bookcases contain books on and from China, while the kitchen is stocked with the finest tea, also from China and Taiwan. You climb to the third floor and find yourself in a room that is covered from top to bottom on all four walls with Chinese calligraphy, quotes from the Book of a Thousand Characters – the most famous model of Chinese writing. Here, for a brief moment, you may feel as if you have woken up in the middle of a book like Alice in Wonderland.
