1Wash all vegetables thoroughly. Cut the Chinese cabbage into large chunks, daikon radish and carrots into thick batons, and trim the ends of the green beans. Spread them on a clean surface or rack and air-dry for 2-4 hours until the surface moisture evaporates.
3In a large pot, combine the filtered water, 80 grams of salt, rock sugar, Sichuan peppercorns, dried red chilies, star anise, and Shaoxing wine. Bring to a boil, stirring until salt and rock sugar dissolve. Reduce heat and simmer for 5 minutes. Remove from heat and let the brine cool completely to room temperature.
