The real zoo is a few kilometers west, also known as Zoologischer Garten. The time between the appointment and the embassy is in the afternoon, so I just wander around first. Two stops westward along the zoo road saw an unnatural building. Two Indian elephants are under the hat of the Harmony Architecture. At first glance, it is a work full of Orientalism in the late nineteenth century. Yes, here it is. This is the famous Berlin Zoo. The primates at the Berlin Zoo are really very lively, especially second-rate. There was a chimpanzee, just a sheet, and then jumped down from the table, pulled and twisted into twists, and played for ten minutes without stopping. I gradually changed from amazing to "come on, let these two force themselves to play" and then went to see the polar bear. In 2008, a wonderful documentary called Knut and his friends told the story of a polar bear at the Berlin Zoo. Unfortunately, just three years after the documentary was released, four-year-old Knut died in front of more than 600 tourists, reportedly due to encephalitis. And when I saw some polar bears at the Berlin Zoo now, I no longer worried about their little companions in the Arctic. In the hot summer days, I wear T-shirts and have become tired dogs. They are wrapped in bearskin coats, chasing and playing on the open-air rockery, running happier than anyone else.
