The number on the peony cigarette butt is the serial number.

Peony is a cigarette brand of Shanghai Tobacco Group. In 1969, Shanghai Cigarette Factory redesigned the "Peony" trademark and launched a red peony flower, also known as "Red Peony".

In 1998, Shanghai Cigarette Factory produced 1.032 million large boxes of cigarettes. During the "Eighth Five-Year Plan" period, the cumulative tax profit exceeded 10 billion yuan, and the quality inspection pass rate was 100%. "Peony" cigarettes have won titles such as Shanghai's "Golden Bull Award" and "National Famous Cigarettes". "Mudan" brand cigarettes have a long history of 80 years and are a well-known best-selling brand in the country. "Mudan" brand cigarettes are flue-cured cigarettes, which are carefully manufactured from high-quality medium and top-grade tobacco leaf raw materials.

The packaging design uses the alluring national color peony as the main pattern of the trademark, which is quite charming. This product has a rich smoke aroma, moderate strength and a comfortable aftertaste, adapting to the tastes of the majority of consumers.
