As China has the very long history, so the ancestors have figured out many ways to make record of the weather. With the regular marks, people can know the time and weather correctly. When summer comes, the hot weather begins with the time of Lesser Heat. So people know what they should prepare in the coming hot whether.
由于中国历史悠久，所以先辈们想了很多办法来记录天气。有了规律的标记，人们就能准确了解时间和天气。当夏天到来时，热天气以小暑开始。所以人们知道他们应该为即将到来的高温做点什么准备。

In my family's tradition, my mother will cook the Chinese watermelon soup for us. She believes that it can drive away the heat in our body. One time, I doubted that function of this soup, then my mother told me that she didn't cook the soup one time and in that year, she got a fever. So she believed strongly that we should eat the Chinese watermelon soup, or we would get a fever easily. 
按照我家的传统，我妈妈会为我们做冬瓜汤，她相信冬瓜汤能驱走我们体内的热气。有一次，我怀疑这汤的作用，然后我妈妈就告诉我她有一次没做这个汤，那一年，她发烧了。所以她坚信我们应该喝冬瓜汤，否则我们就会很容易发烧。

I admire the ancestors' wisdom. They found a way to record the time without high technology. The found of Lesser Heat helps people to get away from the hot weather and let people prepare some work for their crops. The tradition still works no matter how fast the society develops.
我钦佩先人的智慧。他们找到了一种不用高科技记录时间的方法。小暑的发现有助于人们远离炎热，让人们为他们的庄稼做一些保护工作。不管社会发展得多快，这个传统仍然有效。
