Memories of past events 70 years ago: a glimpse of a naked man in a wine-making workshop

Memories of past events 70 years ago: a glimpse of a naked man in a wine-making workshop

Last night, I studied "production of bioethanol from maize" ("Making bio-alcohol with corn") and recalled a period of past in my childhood.

I was naughty when I was about 6 years old. One day, I made an appointment with a partner (the little name is "Stone") and secretly sneaked into a courtyard, wandering around in it. Later, we found a big room with sound in it. We can see that there are a lot of men who don't wear clothes, they don't need to wear clothes, and they are sweating. They are constantly stepping up and down in a large pool. The two of us were shocked. I don't know why these men don't wear clothes and dance "?

After reading this article last night, I realized that the naked men were "making wine" (Manual Fermentation Process ). In fact, the use of corn (maize) for liquor (ethanol), generally through the grinding, liquefaction, fermentation, distillation and other processes. Today, bioethanol manufacturing processes in the United States are exactly the same as those in small wine-making workshops 70 years ago. Why did North China go to the United States to "steal seeds "?

At noon yesterday, the Children celebrated my birthday in Wangjing New World, Beijing. I had a bad time. Because Beijing's new world tower is no less prosperous than Paris, France, but I am still recalling the past time (poor days), the contrast is too big, I can't stand such noisy and prosperous scenes.
