Traditional Chinese Medicine (TCM): In TCM, summer is associated with the Fire element (火, huǒ), the heart (心, xīn), and the emotion of joy (喜, xǐ). It's a time of peak yang (阳) energy, representing outward expression, growth, and maximum activity. The cultural focus is on staying cool and balanced, not just through air conditioning, but by consuming “cooling” foods like watermelon and mung bean soup to counteract the body's internal “heat.”
Escaping the Heat (避暑, bìshǔ): The oppressive heat and humidity in many parts of China make “escaping the heat” a major cultural practice. People flock to cooler mountain resorts, seaside cities like Qingdao, or even air-conditioned shopping malls and libraries to find relief. This is a common topic of conversation and a major driver of domestic tourism.
Comparison to Western “Summer”: While Western cultures often associate summer with long, leisurely vacations, beach parties, and a general slowdown, the Chinese 夏天 (xiàtiān) has a slightly different rhythm. It certainly includes holidays and fun, but it's also bracketed by intense national events. The season kicks off with the grueling national college entrance exams (高考, gāokǎo) in June, which puts the entire country on edge. This is followed by the long summer vacation (暑假, shǔjià) for students, a time for travel, family visits, or extra tutoring. The feeling is less about a complete “break” and more about a different kind of activity and energy.
