In other places, there are symptoms of oral ulcer and throat inflammation, but in Guangdong, Cantonese people will only say "You are hot" and "You are getting angry". Hot air means high-temperature gas, which is a lot of symptoms, all of which are caused by high temperature and humidity in Guangdong, so hot air usually covers symptoms such as sore throat, acne and constipation.
generally speaking, there is less habit of drinking tea and making soup in the north, but in Guangdong, you can see some herbal tea shops there, and many Cantonese dishes are mainly light. Therefore, in this hot and humid Guangdong, we must pay attention to the usual diet, otherwise it will be easy to "hot" in summer.
