In the second year of Zhenguan, there was a locust plague in Guanzhong, and the people exchanged their children for food. Li Shimin went to the courtyard outside the city incognito and saw someone exchanging grain and fine salt for locusts. That night the lady in the courtyard climbed through the window and entered his palace: Your Majesty, locusts can be fried and eaten. She took out the love letter and knelt down to hand it over: My daughter has ten strategies to eliminate locusts, and she boldly asks to see her. She unbuttoned her collar to reveal red rashes all over her body: she was poisoned when she tasted it, take a look. She grabbed his hand and put it on her neck.
