On the autumn night of the 16th year of Yongle, a loud bang interrupted Zhu Di's review of the memorial. An ugly stone about one foot wide fell from the sky in Qianqing Palace, and the smell of blood floated into the hall. Zhu Di put down his ink brush, his mind was in a mess - some people called him a thief, others called him a thief. He compiled the Yongle Dadian and drove the Tatars to the north of the Great Wall. How many emperors since ancient times can compare with him? Jin Yiwei exited, leaving only him and the stone that fell from the sky.
