【Learn Chinese】How China Survives the Great Summer Heat

If you thought the plum rain season was humid, wait for what comes next. By mid-July, southern and eastern China enter the hottest stretch of the year, marked by two solar terms:
小暑 (xiǎoshǔ) — Minor Heat — and 大暑 (dàshǔ) — Major Heat. Together with the 40-day 三伏天 (sānfútiān) — "three fu days" — they make up the period when the sun blazes, pavements bake, and every conversation starts with complaining about the temperature.

For over 2,000 years, Chinese people have not just endured this heat — they have built a whole seasonal culture around coping with it. Traditional wisdom says this is a time to slow down, avoid midday sun, and eat according to the season. The most famous rule is “冬病夏治” (dōng bìng xià zhì) — “treat winter illnesses in summer.” Many people apply herbal 三伏贴 (sānfú tiē) — medicated patches — to their backs, believing the summer heat opens the pores and lets the medicine absorb deeper to prevent colds and joint pain in winter.

Food is the centerpiece of summer heat culture. Every household makes 绿豆汤 (lǜdòutāng) — mung bean soup — boiled until the beans split, then chilled and sweetened. It is the default home remedy for heat exhaustion. On the street, vendors sell 酸梅汤 (suānméitāng) — sour plum drink — a dark, tangy-sweet infusion of smoked plums, licorice and rock sugar that has been a popular cooling drink since the Song Dynasty.

Modern life has added its own rhythms. Office workers rely on 空调 (kōngtiáo) — air conditioning — so heavily that cities often issue power supply warnings during peak heat. Street life shifts entirely to the evening: 夜市 (yèshì) — night markets — don’t get busy until 9pm, when the temperature drops a few degrees. Families walk around parks after dark, and late-night barbecue stalls stay open until 2 or 3 in the morning.
Locals also swear by small daily hacks: drinking warm tea instead of ice water (traditional belief says cold drinks shock your system), taking a short 午觉 (wǔjiào) — midday nap — to avoid the 12–2pm heat peak, and wearing light linen clothes in light colors.

The great heat passes eventually, but for the four weeks it lasts, it shapes almost every part of daily life. It is not just weather — it is a shared experience that turns every stranger on the street into someone who understands exactly how you feel.
