巜正大大学》Translation:

A countryman in Zheng State learned to make rain gear. He learned it in three years, but when there was a severe drought, the rain gear he made was useless. He gave up rain gear and started learning Jumei. He practiced it for three years, but it rained heavily and it was useless again. So he went back and redid the rain gear. Soon thieves started to appear in droves, and people all wore military uniforms. Military uniforms can protect against rain, so few people used rain gear. He wanted to learn to make weapons again, but he was old and couldn't do it anymore.

There was a man in the State of Yue who was good at agriculture. He reclaimed wasteland and cultivated fields to grow rice. However, he encountered floods every three years. People said that the land should be drained and planted with millet instead, but he refused to listen and continued to plant rice without changing. The drought lasted for two more years. He calculated the harvest and found that he had made up for the previous poor harvest and still had a surplus. Therefore, it is said: "When there is a drought, you need to prepare ships; when it is hot, you need to sew fur clothes. It is really a famous saying in the world." For cover. There was a severe drought for three years, and it was useless and turned into straw. It rained heavily for three years and was of no use, so it was still a cover. Not long after, robberies started, and all the people used their military uniforms, leaving only those who could use them. If you want to learn to be a soldier, you will be old. The more good farmers there are, the more they dig fields to grow rice, they will suffer from waterlogging for three years. People say that it is better to drain the water to plant millet, but they don't listen, and if it remains the same, it means that there has been a severe drought for consecutive years. If you calculate your gains, you will pay for your losses and win. Therefore, it is said: "Dry people have boats, hot people have furs. This is a famous saying in the world!"
