If the bamboo cane water is stored at room temperature, it will take about one day. The water boiled from the bamboo poles and horseshoes of Maogen needs to be stored in the refrigerator in summer, otherwise the soup will easily deteriorate and ferment. If it is autumn and winter, it will only be stored for one day at room temperature. You can keep it in the refrigerator for two days regardless of spring, summer, autumn and winter.
