At the end of World War II, after the Allied Countermeasures Committee against Japan was established, "Rao Jiazhong", the inventor of Shanlin Big Red Sausage, followed his father "Rao Diqun" (the seventh phase of Huangpu Military Academy and deputy commander of the Honorary Second Division of the National Revolutionary Army) by plane from Vietnam's coastal defense.

Nanjing was transferred to Shanghai, and when he was waiting to be stationed in Japan, his father's army was suddenly temporarily thrown into the battlefield of the civil war. Rao Diqun moved to Taiwan alone to resist the civil war. His political career was blocked and he lived in poverty. He made a living by selling braised food in his hometown.

By chance, I helped a Viennese chef "Schwarraus"... The grateful Schwarraus taught Vienna's most famous red sausage making technique to Rao Dikun... Rao Dikun made several improvements.

Red sausage with hometown flavor, I hope to bring it back to my hometown one day.

After the reform and opening up, Rao Jiazhong went to Taiwan to visit his father after many twists and turns.

I learned that my father’s greatest wish was to bring back his medal of honor in the first half of his life and the hometown-style red sausage he invented in the second half of his life back to his hometown!

Rao Jiazhong returned to Shanghai with his father's trust and developed a large red sausage with a strong Shanghai flavor based on his father's red sausage making process.

Because "Rao Jiazhong" owned a cooked food chain company Shanlin Delicatessen in Shanghai at that time, this big red sausage was also called "Shanlin Big Red Sausage".

Shanlin's red sausage has good elasticity, tender meat, rich nutrition and rich flavor. Once it was put on the market, the supply exceeded the demand. It was deeply loved by Shanghai residents and became popular throughout Shanghai. It has become Shanghai's local gourmet business card.
