Let's briefly talk about some things about the Sui Dynasty. We have little knowledge and talent, and we dare not talk too much. We care about history from different angles. We focus on the social details at that time, such as fireworks, what people ate, what methods were used at that time, tableware, clothing, and living environment. These are inseparable from the social environment and the policies of the rulers. We try our best to introduce things in a colloquial manner to make it easy to understand.
