Official weather

First, there is a detail in the construction of ancient residential buildings, which is difficult for people to notice because it is too common. That's it? Tall and dense? ,? Tall? It blocks the sunlight well, making the air below very cool, and people can also hide in cool places. ? Secret? Can make the gap between houses very narrow, it is easy to increase the circulation of air! Yes, the narrow space is easy to increase the air circulation, because when the air passes through the narrow alley, it will be squeezed because of the lack of space, which will increase their flow speed, so the alley is particularly cool!

Don't underestimate the summer effect brought by these two points, even in modern air-conditioned life. It is for this reason that the air conditioning in the city turns day and night, so it is better to lay a summer mat at the alley mouth in the countryside. And the most important thing is that the house is very high, which makes the part near the ground special? Yin? , this kind? Yin? It is the main ability of the ancients to escape the heat in summer. It is for this reason that many people suddenly feel chilly when they walk to the ancient buildings during their visits.

Second, the ancient ice room is very powerful. How powerful is it? Ice cubes that can be collected in winter will be released in summer! It's just that most people make two pairs of delicious food with ice cubes? Popsicle? To make money, only those rich people will choose to use ice cubes to cool down for the summer. However, it can also be seen that in ancient times, it was not as backward as imagined. At least people have popsicles to eat.

Third, there are many green trees. Finally, it was not so hot in ancient times, because although trees were cut down, the damage to greening was limited, and people's main property often came from crops and planting some trees, and so on. As a result, the greening in ancient times is incomparable today. At least in the places where human beings live, greening is much better than modern times. So although it was hot, there was a cool smell in the air.
