Beijing Zoo
The zoo sent staff to study zoo management in the Soviet Union and Poland, and began to trade animals with Eastern Bloc countries, Burma, India, Indonesia, and Japan to expand its collection. Zoo staff used some 30 species from the zoo including South China Tiger, François' langur, Chinese alligator, python and black bear in such trades. The Moscow Zoo and Leipzig Zoo donated 14 species including African lion, polar bear, brown bear, emu and Himalayan vulture. The park was renamed the Beijing Zoo in 1955. Guo Moruo, the renowned writer and president of the Chinese Academy of Social Sciences wrote the calligraphy for the zoo's entrance sign. Leading Chinese universities also established a research presence in the zoo to study animal behavior and to breed endangered species. Giant panda was displayed at the zoo for the first time in 1955 and successfully bred by zoo staff in 1963.
