It's that Yang Meimei likes to eat this litchi, and then it's far away. You know, litchi is delicious only when it's fresh, but in ancient times, the preservation technology didn't pass the mark, so she hurried on, killing people and horses.

The writer Su Shi has a poem "Litchi Sigh", which describes the scene of Yang Guifei eating litchi at that time. The poem sighs: "Flying across the mountains and storks across the sea, the wind and leaves are like new flowers. When the beauty in the palace broke her face, she was shocked by the dust and spilled blood for thousands of years. " Many people put their lives in the relay races that ran across the hills and rivers again and again, resulting in "shocking dust and spilling blood". Finally, litchi was spread to the palace as if it were newly picked. Mr. Su Lao's poetry can be summed up in a vernacular: the lychees that Yang Guifei filled into her mouth were soaked in other people's sweat and blood.
