After Time Travel, I Became Princess Qin

What should I do if I wake up and find that I have traveled to the Qin Dynasty? As Brother Zheng's crush, of course she tried every means to meet him and planned to marry him. She told him that Wang Jian should be used directly when going to Chu State, which would save troops and horses. She reminded him to guard against Lu Buwei as soon as possible to consolidate the royal power. He also warned him that when Yan State came to present a map, he should let the guards open it. Check the map carefully, remind him to pay attention to his health when he forgets to sleep and eat while reviewing memorials, help him simplify Chinese characters, annotate and compile books, and write a true biography of him to prevent him from being misunderstood by future generations. Maybe history will be different because of this... Intention: fun
