Tofu is a kind of popular food in China. Here is one of the stories about how it was invented.
In the Han Dynasty, there was a man who loved his parents very much. But they were so old that they could only eat soft food, so the man decided to cook some soybeans (大豆)for them. He mashed(磨碎)the soybeans and made them into soup.
The soybean soup didn't taste very good in the beginning because there were too many soybean crumbs(碎屑)in it. The man took the crumbs away, but his parents still didn't like it. He thought and thought many times. At last he added some salt and heated it again. After the soup cooled down, it changed a lot. The unusual taste is very good and the man was satisfied with it. His parents loved it very much. After that, he invited his relatives to taste it. Finally, people around the country all learned how to make tofu. And the invention plays an important role in our dinner table.
