Introduction to Kong Mansion: Kong Mansion, the residence of Kong Xiangxi, is located at No. 250, the northernmost end of Duolun Road. It was built in 1924. After the victory of the Anti-Japanese War, it was used as the residence of Kong Xiangxi, so it was called the "Kong Mansion". The building's facade and interior are in Islamic Spanish style. Kong Xiangxi is the third of the four major families of "Chiang, Song, Kong and Chen" in old China, the 75th generation descendant of Confucius, and the husband of Song Ailing (it is said that Song Ailing was "robbed" by Kong at a dance, and it was the two of them who first met Washington. Interesting anecdotes from the time). He has successively served as President, Vice President, Minister of Finance, and President of the Central Bank of the Executive Yuan of the Guo_Min_Dang Government. People use the term "acquisition of wealth" to summarize the Kongs' outlook on life. The couple's private property ranked first among the "four major families", and it is not an exaggeration to say that they were the richest family in China at that time. Kong Xiangxi, Song Ailing and his wife have four mansions in Shanghai, and the "Kong Mansion" on Duolun Road is just one of them.
