What is Yibin "Xu Fu's old crap"?

Yibin "Xu Fu's old crap" is a fermentation & aging documented in the Chinese Practical Production Technology collection. The entry keeps the original material list, quantities and sequence, so you can follow the method as printed.

Is this an authentic Chinese method?

Yes. The underlying text is from mainland Chinese workshop literature aimed at small producers and home makers; the English on this page is a direct translation with the original numbers and steps preserved.

What do I need to get started?

Standard kitchen or workshop vessel, the raw materials in the stated ratios, salt or starter as listed, and somewhere to hold the batch at a stable temperature.

How long does it take?

The timing depends on your climate, batch size and equipment rather than on the text; the source records the process sequence rather than fixed hours, so follow the stages and check the material state at each one.

Can I run this as a small business?

Many entries in this collection were written with small-scale and home production in mind. Before selling, confirm the food-safety, labelling and local-registration rules that apply where you operate.
