Of course, there have been locust plagues in China's history, and many times. Thanks to the unremitting efforts and joint management of workers for thousands of years, the locust plague has been controlled, so that in modern times, locust plague rarely occurs. As for why Emperor Taizong and Li Shimin ate grasshoppers, it was actually because of the plague of locusts. Speaking of grasshoppers, I can't help sighing. When I was a child, I always thought that grasshoppers were grasshoppers and grasshoppers belonged to another species, but unexpectedly, grasshoppers were called grasshoppers. Once they appear everywhere and cause disasters, they change from grasshoppers to locusts ...............................................................................................................................................................

China has been a great river civilization since ancient times. And river civilization depends on farming and animal husbandry. Therefore, farming can be said to be the foundation for farmers to settle down in China, and once a disaster occurs, the locust plague will undoubtedly be a fatal blow to agriculture in China. Wherever locusts went, nothing grew. When the ancients encountered this situation, they felt that the emperor at that time was heartless, so disaster fell from the sky. But this is not the case. The plague of locusts is a natural law.

Besides, Li Shimin is a wise king. During his Zhenguan years, it was not without locusts. According to Zi Zhi Tong Jian, one year, the capital of the Tang Dynasty was hit by locusts. When Li Shimin went to the garden, he found that there were many locusts even in the royal garden, so he took bold actions. He actually caught a few locusts, and then said that these crops are the basis of people's life and survival. If these locusts eat these crops, people will not survive.

So he wants to eat these locusts. He would rather let locusts eat his entrails than let locusts eat crops. When the ministers and guards saw this scene, they immediately dissuaded Li Shimin from doing so. Li Shimin righteously rejected them, saying that he was helping people avoid disaster, and then he ate the locusts raw.
