Introduction to Hunan Villa: There is a Spanish-style garden house at the intersection of Wukang Road and Hunan Road. This is the Hunan Villa, the residence of Zhou Fohai, a traitor who served as Minister of Finance and other important positions during the Wang puppet regime. Hu Lancheng, then deputy director of the Propaganda Department of the Wang Puppet Government, visited the Hunan villa many times with his wife, Zhang Ailing, a well-known beauty writer in Shanghai. During a visit, Zhang Ailing heard the legendary story of the Central Command using a beauty trap to send beautiful woman Zheng Ruping to assassinate Wang Puppet official Ding Mocun, and later wrote the book "Lust, Caution".
