China's 'Minor Heat' Period Begins, Signaling Increased Summer Temperatures

The 'Xiao Shu' (Minor Heat) period in the Chinese lunisolar calendar began on July 7, signaling the official start of high summer. During this time, temperatures rise significantly, and many regions across China experience hot and humid conditions, often referred to as 'sauna days.'

Xiao Shu often coincides with the beginning of the 'three hottest days' of the year and marks the end of the plum rain season in the Jianghuai region. Simultaneously, Northern China and Northeast China transition into a rainier season. Both climatic conditions and agricultural practices shift; crops enter a rapid growth phase, necessitating intensified field management.

Traditionally, Xiao Shu is associated with specific dietary practices, such as eating dumplings on the first day of the 'three hottest days.' The diet emphasizes cooling foods like fruits and vegetables, or soups and porridges to help combat the heat. Some traditions also advise against sitting on wooden furniture left outdoors due to moisture.

Adaptation to the hot climate is also highlighted through folk customs. Certain areas consume lamb or 'overcooked' noodles to ward off the heat. Traditional farming methods and preparations for harvest are also crucial during this period, as farmers step up efforts to ensure optimal growth.
