Fu Caiyun (1872—1936 AD) was nicknamed Sai Jinhua (literally meaning surpassing golden flower). When a little girl, she was sold to a whorehouse in Suzhou city. In 1887 AD, she was taken by a high official Hong Jun (1839—1893 AD) as his concubine at the age of fifteen while Hong was forty-eight. Next year, Hong Jun was sent to Russia, Austria, Germany and Holland as an envoy of Qing dynasty. She went with him as his Ladyship because his wife did not like to live in foreign countries. She lived in Berlin for a few years. She had been to St. Petersburg and Geneva. So she had known some German officers.
When her husband died, the family did not welcome her as she had been a whore. She had to leave and become a whore again for her living. At first she went to Shanghai, and later she went to live in Tianjin city, close to Peking. When she was a whore, she was known by her nickname, Sai Jinhua.
In 1900 AD, when the allied forces came to Peking, she was living there and had some good relationship with some German officers. It was said that she was familiar with Alfred Graf von Waldersee, the commander of the German troops. She had even tried to dissuade him from burning the Yuanming Garden. In 1903 AD, a young whore was ill-treated to death by her, and so she was arrested. Then she was sent in custody to her hometown, Suzhou city, for the service. When she was released from jail, she went to live in Shanghai. Afterwards, she moved to Peking and led a poor life till she died of severe disease there in 1936 AD.
