If I made no mistake, I am sure what you try to imply is the ruler of Qin. If so，I have to say there are several historical mistakes about the notes he left, for there' re something he could never know as a slumpering king.
First：Chinese in Qin Dynasty have no paper to use, but the parchment is unusual either, or even maybe not existed as a way of recording. They just use bumboos or wooden blocks connected by ropes to write and record, something simliar to scrolls.
Second: Ancient Chinese know nothing about glass, what similar to it may be cystial or gems, there are actrually an cystial artifict, which is a transparent cup made of clean cystial be found in a ancient tomb older than Qin Dynasty. Either way, no glass exist at that time.
Third: I don't know if you're intented, but as a ruler of ancient Chinese dynasty, one only calls themselves as "孤"(longly)、“朕”(not-perfect)、“寡人”（longly one）and so on. These tiltes are literally negtive and strange, for they have to show their "Modesty"; Aslo a styled reprenstion for holding the Apex-power. It's some thing similar to "Royal we", and they will never just call themselves as "I" or "Me", as long as they still wanna to rule the world.
