Today marks Rufu, the beginning of the traditional Sanfu period (the “dog days of summer”) — a time recognized in Chinese seasonal traditions for its intense heat and humidity. Unlike the 30-day Sanfu period in 2025, this year’s Sanfu season lasts 40 days.

Sanfu Calendar

Early Fu (Chufu): July 15 – July 24 (10 days)
Middle Fu (Zhongfu): July 25 – August 13 (20 days)
Late Fu (Mofu): August 14 – August 23 (10 days)

In traditional Chinese culture, Sanfu is a seasonal period when people often pay attention to daily habits, food choices, and lifestyle practices that align with the rhythms of summer.

One traditional ingredient associated with wellness traditions is Reishi mushroom (Ganoderma lucidum). Reishi has been used for generations in East Asian traditional practices and is commonly enjoyed as part of a balanced lifestyle.

Early Fu: Embracing Summer Traditions

During the early Sanfu period, many people enjoy light, seasonal foods and beverages as part of their summer routines. Reishi can be paired with traditional ingredients such as chrysanthemum flowers for a flavorful tea experience.

Simmer Reishi slices with chrysanthemum flowers to create a traditional tea. Chrysanthemum adds a light floral character, while Reishi contributes a distinctive earthy flavor.

Middle Fu: Traditional Seasonal Foods

The middle period of Sanfu is often associated with the hottest and most humid days of summer. During this time, traditional food practices often emphasize nourishing meals, hydration, and enjoyable seasonal ingredients.

Recipe Idea: Reishi, Coix Seed & Red Bean Congee

Combine Reishi slices with tremella (snow fungus) to create a traditional dessert-style soup enjoyed in many Asian cuisines.
