There is a book devoted to the disaster in the Lu Yu border region at that time.
The locust plague lasted for nearly three years, and no one dared to take care of the absurd things. Because locusts locusts are just homophonic with the emperor. In ancient times, even the name of the emperor was taboo, and everyone should avoid it when naming it, not to mention the word "emperor" directly.
After all, the ruler of the dynasty has always advocated the divine right of the imperial power, which means that his rights are given by heaven and he himself is an angel sent by heaven. Ignorant officials think that maybe it is his poor governance, and these bugs are sent by heaven to punish them ... so the disasters continue to increase.
A large number of hungry people began to leave their homes and ran to the nearest places in Shandong, such as Henan, Beijing and Tianjin. The influx of a large number of victims, while the population is flowing, has also improved the sense of crisis of the rulers. After all, rabbits bite when they are in a hurry. These homeless victims have brought great hidden dangers to the capital. What if the surging emotions overthrew his throne?
Therefore, Emperor Xuanzong of the Tang Dynasty began to discuss with the Prime Minister to eliminate the plague of locusts. Through human capture and the cold weather at that time, the living conditions of locusts became worse and worse. The plague of locusts finally ended at the end of the third year of Kaiyuan, and Shandong began to recuperate after being seriously injured.
But it didn't last long. In the spring of the fourth year of Kaiyuan, the plague of locusts swept through again, even more serious than before. After the last incident, the local ignorant secretariat thought it was a punishment from heaven, and Shandong was once again in dire straits.
