the oldest room was the earliest place to open Su-style cakes. In the 22nd year of Qing Daoguang (1842), Chen Kuifu, a native of Jiading, opened a cake group shop in Dongzhadu Catholic Street in Nanshi, formerly known as Chen Dafang. He started the cake group, and because of his superb skills, his business was booming, he later partnered with others to produce and sell Soviet-style cakes and sweets. In the first year of Xianfeng (1851), it was renamed Laodafang; Later, Laodafangbei was added to the mouth of Nanjing Road Pot Tangnong; In the 1th year of the Republic of China (1921), we expanded our partnership and moved to the intersection of Nanjing Road and Fujian. Because there are many tea shops with the same name, it was named Laoda Housing Association. Later, the tea shops were: the Soviet-style old house in the west and the old house in the west gate

In the early years of Guangxu, Shanghainese Chen Wantai opened a tea shop in Dongjiadu, Nanshi, and named it "Chen Dafang". In the 28th year of Guangxu (192), the employee Chen Kuifu entered the store and renamed it "Laodafang". In the early years of the Republic of China, he moved to the intersection of Nanjing Road and Fujian, where his business was distinctive, his business was booming and his brand was getting louder and louder. The eldest brother's room became famous, and as a result, a number of "eldest brother's rooms" sprang up like mushrooms after rain on the beach, making it difficult to distinguish between true and false monkey kings.

There were many food stores in the old house, and Chen Kuifu's old house was almost flooded, so the real and false old house started a lawsuit. The old house was profitable, and no one would give up. Everyone said that their old house was the earliest and the brand was the oldest, but there was no trademark registration system at that time. For a time, the old house became a "difficult problem", so the Bureau of Commerce had to consult the archives of the hydropower company, and the result confirmed that Chen Kuifu's old house was the earliest. Today's real old house is a famous and excellent store in Shanghai's commercial system. The enterprise integrates retail and self-selling, selling tobacco and alcohol, North and South goods, cakes, roasted seeds and nuts, sweets, cured products and so on. Produced and sold smoked fish, smoked goods, Mid-Autumn moon cakes, fresh meat moon cakes and Soviet cakes.
