After the Emperor's death, Prime Minister Li Si, who accompanied him, became extremely worried that the news of his death could trigger a general uprising in the Empire. It would take two months for the entourage to reach the capital, and it would not be possible to stop the uprising. Li Si decided to hide the death of the Emperor, and return to Xianyang. Most of the Imperial entourage accompanying the Emperor were left ignorant of the Emperor's death; only a younger son, Ying Huhai, who was travelling with his father, the eunuch Zhao Gao, Li Si, and five or six favourite eunuchs knew of the death. Li Si also ordered that two carts containing rotten fish be carried immediately before and after the wagon of the Emperor. The idea behind this was to prevent people from noticing the foul smell emanating from the wagon of the Emperor, where his body was starting to decompose severely as it was summertime. They also pulled down the shade so no one could see his face, changed his clothes daily, brought food and when he had to have important conversations, they would act as if he wanted to send them a message.
