I think there are many. For example, the painting of Dong Cheng meeting Xun Yu that Cao Cao burned was what Guo Jia showed to Cao Cao in the first episode. In fact, Cao Cao knew about it all along and was just waiting for Xun Yu to take the initiative to talk to him. At the end of the seventh episode, when Cao Cao and his wife Bian were talking about the marriage between Cao Pi and Cao Zhi, Cao Cao was scraping the words on the bamboo slips with a book knife. After checking, it was found that what was written on the bamboo slips was a passage written by Ban Gu to his younger brother Ban Chao. I was a little surprised at the time. The plot happened to be about brothers Cao Pi and Cao Zhi.

After continuing to search, I found that this was actually the article "Classics·Thesis" written by Cao Pi. Baidu says this is the first literary monograph in the history of Chinese literary criticism. At this point, I have to admire and appreciate the director's sincerity, and the details are simply meticulous. Although my ability is limited and I cannot interpret the meaning of this article in the play, I was still amazed by the director's delicate thoughts. I hope to see more exciting details in the future.

Yang Xiu is going to entertain his colleague and friend Ding Yi at home today, and he is preparing a sumptuous barbecue feast. There is a dedicated maid nearby to fan the flames and pour wine. At that time, barbecue was mainly done by skewering meat on skewers, much like today’s skewers in summer. Of course, delicacies such as barbecue were only exclusive to the families of aristocratic officials at that time, and ordinary people were not blessed to enjoy them and then sprinkle some seasonings on them. Considering that cumin was only introduced to China from the Western Regions in the Tang Dynasty, seasonings such as salt and pepper should have been sprinkled at this time.

Exquisite barbecue is delicious, but it was also a luxury in the Han Dynasty. Even the princes and nobles could not treat it as a daily diet. That night, the Prime Minister's Mansion prepared a daily dinner for Cao Cao. Because it was eaten every day, the dinner was not rich, but it was delicious. Boiled noodles, paired with several blanched vegetables, and some seasonings or sauces are a delicious bowl of Eastern Han Dynasty noodles.

Although the taste is a little bland, it has a smooth texture and is considered a delicacy when used to satisfy hunger. While enjoying the meal, Prime Minister Cao accidentally dropped a piece of dough on his clothes. On his robe, Prime Minister Cao quickly picked up the noodles and stuffed them into his mouth while no one was paying attention. Even in the prosperous Han Dynasty when the treasury was full and people had plenty of food and clothing, food was still extremely precious. Cherishing food was something everyone from the common people to the nobles would do in that era. After using up the dough, pour hot water into the bowl with some leftovers, and it became a simple bowl of after-dinner soup.
