Why Chinese food turns cold in summer
The first August I spent in Hangzhou, I expected heavy food and was surprised to find people eating bowls of cold noodles and drinking pale green soup straight from the fridge. Chinese cooking has a whole branch built around cooling the body during heat, and it’s not just about temperature. The logic comes from traditional ideas about balancing the body, but you don’t need to buy into that to enjoy it. The practical point is that summer in most of China is hot and sticky, and the local food adapts with cold dishes, light broths, and fruit-based sweets.
This is a traveler’s guide, not a medical one. I’ll tell you what people actually eat when it’s 35 degrees and how to find it, with names and prices. Some of these dishes show up year-round but are at their best in summer.
Cold noodles and the wheat belt
In the north, summer means liangpi (凉皮), cold wheat or rice sheets dressed with vinegar, garlic water, chili oil, and cucumber. A bowl in Xi’an or Lanzhou runs RMB 8-12 from a street cart. The version in Xi’an is thicker and chewier; the Gansu version is lighter. I ate liangpi almost daily during a July trip through Shaanxi and it kept me going when hot meals felt impossible.
Then there’s zhajiangmian served cold, cold soba-like noodles in the northeast, and the cold sesame noodles of Shanghai. The throughline is starch plus acid plus a little fat, which is exactly what sits well in heat. The wider picture is in the types of Chinese noodles, but for summer the cold ones are the move.
Cold drinks that aren’t soda
Green bean soup (绿豆汤, lvdou tang) is the summer staple I underestimated. It’s a sweet, room-temperature or iced soup of mung beans, sold at every convenience store in summer for about RMB 4 a cup. It tastes like a mild, slightly grassy sweet soup, and it’s genuinely refreshing. Homemade versions in the south add a little kelp or lotus seed.
On top of that, the Chinese tea culture shifts in summer. Cold-brewed green tea and the herbal liang cha (凉茶, “cooling tea”) of Guangdong are everywhere. The Cantonese herbal tea shops are an acquired taste, bitter and medicinal, but locals swear by them for heat rash and sore throats. A cup costs RMB 5-10.
Fruit and the wet-market run
Summer is fruit season across China, and the cheap stuff is excellent. Watermelon (西瓜) is the default, sold by the half or quarter from street carts at RMB 2-4 per jin. Hami melon from Xinjiang shows up in the east by July. Lychee and longan hit the south in June and July; I had the best lychees of my life at a roadside stop outside Guangzhou, sweet and floral, for almost nothing.
The wet markets are where fruit is cheapest and freshest. Go in the morning, pick what’s local, and skip anything flown in from far away. A knife and a plastic bag later, you’ve got a picnic.
Cold desserts and sweet soups
The south does the best summer sweets. In Hong Kong and Guangzhou, mango sago (杨枝甘露) with pomelo and coconut milk is the air-conditioned treat, about RMB 20 in a cha chaan teng. In Chengdu and Chongqing, the cold glutinous balls in brown sugar (冰粉) come topped with fruit and crushed peanuts, a cooling counter to the chili. The Chinese desserts guide covers the wider range, but for heat relief the chilled ones win.
Another one: the grass jelly (仙草) of Taiwan and the south, a near-black jelly made from a mint-family plant, served cold with syrup. It tastes faintly of liquorice and cools the mouth fast.
Light broths vs heavy ones
Even the soup course shifts. Winter broths are rich and gelatinous; summer ones are clear and sour. The cold cucumber salad with smashed garlic is on every table. A light congee at breakfast, plain or with Century egg, sits easier than fried rice when it’s humid. And the Chinese herbal soups thin out in summer, using pear and fig instead of the heavy tonics of winter.

A note on the “cooling” theory
You’ll hear locals talk about “hot” and “cold” foods in the traditional sense, which has nothing to do with temperature. I won’t pretend to verify the physiology. What I can say is that the summer dishes above are lighter, colder, and easier to digest, and that matches what my body wanted in the heat. If you want the deeper soup tradition, the Chinese soup recipes piece explains the double-boiled style that dominates in cooler months.
Vegetarian and the heat
Summer is the easiest season to eat light as a vegetarian in China, because so many cooling dishes are plant-based: cold cucumber, smashed garlic greens, green bean soup, fruit. The vegetarian travel guide has more, but in July you’ll find the markets full of the right stuff. Pickled vegetables also help cut the heat; Chinese pickles add a sour edge that makes warm rice go down.
The herbal tea habit
The Cantonese herbal tea shops are an education. They serve bitter, dark brews meant to clear heat, and the first sip is a shock if you expect sweet. I grew to like the milder chrysanthemum version, which is light and faintly floral, sold cold in summer. The strong stuff is for when you feel a sore throat coming; locals line up for it. Try a small cup before you commit to a bowl, and the tea guide explains the herbs if you’re curious what’s in it. It’s an acquired taste, but on a 35-degree day the cold bitter cup does what a soda never does.
Mistakes in the summer heat
I ate a heavy hot pot in July once and regretted it; the cooling dishes are the better call. I also bought cut fruit from a cart without ice and skipped it after; peel your own. And I skipped the green bean soup and dehydrated by afternoon; the cold soups are water as much as food. Small errors, but the heat magnifies them, so the light dishes aren’t just preference, they’re practical.
Cooling soups beyond green bean
Green bean soup is the famous one, but the south has others. A cold barley and gourd soup shows up in Cantonese homes in August; it’s faintly sweet and very light. The north drinks cold sour plum juice (酸梅汤), a dark, tart drink sold from summer carts for RMB 5, and it cuts heat better than soda. I’d try both: the barley soup after a heavy meal, the sour plum juice walking between sights. They’re cheap, everywhere in season, and more interesting than another bottle of water.
Frequently asked questions
What is the most common summer drink in China?
Green bean soup and cold-brewed tea are the everyday ones. Bottled iced tea and cheap watermelon juice are everywhere too. Herbal tea is regional to the south.
Is liangpi spicy?
It can be. The chili oil is added separately, so you can ask for less (少辣, shao la). The vinegar and garlic are what make it refreshing, not the heat.
Where do I find green bean soup?
Convenience stores (Lawson, FamilyMart, Convenience 24) stock it cold in summer. Street breakfast carts sell it warm or iced in the morning.
Are these dishes safe for sensitive stomachs?
Cold food can upset some travelers. If you’re worried, stick to the hot green bean soup version and peeled fruit. The food safety guide has the baseline rules.
What about cooling foods in dry northern summers?
The north is hot but less humid, so cold noodles and watermelon rule, and people drink more plain cold tea than the bitter southern herbal stuff.
Can I make these at home before the trip?
Yes. Green bean soup is just boiled mung beans with sugar and ice. The congee recipe adapts to a thin cold version if you let it cool.
Do restaurants serve these year-round?
Most do, but the quality and price are best in season. Off-season watermelon is imported and dull; in July it’s local and sweet.
