Read the following material and answer the questions: According to the meaning of the Spring and Autumn Annals, the material is the same as that of the Xia Dynasty and the barbarians outside... Guanzhong was fertile and rich…the capital of the emperor…

The statement in Material 1 reflected the ancient Chinese concept of national security, which was to strengthen the defense and resistance of the surrounding ethnic minorities while maintaining control over the Central Plains. Material 1 further explained the advantages of the Qin State in terms of ruling the region. Guanzhong was the birthplace of the Qin State, fertile land and rich resources. It was also the main traffic route connecting the six countries. It was the target of competition between the countries. Therefore, the Qin State was able to maintain control of the region. Based on the above two points, we can see that the first material reflects the concept of national security in ancient China, which is to strengthen the defense and resistance of the surrounding ethnic minorities while maintaining control over the Central Plains.

Material One said that during the Spring and Autumn Period, China experienced a period of contending with the Hundred Schools of Thought, which had a profound impact on China's history. Material 1 mentioned the phrase " internal Xia and external Yi Di ". It meant that during the Spring and Autumn Period, China had internal Xia and external Yi Di invasions, so it needed to defend against external threats. The barbarians referred to foreign minorities such as Rong Di and Di Yi. Combined with what we have learned, we know that the Spring and Autumn Period is the predecessor of the Warring States Period. China experienced a great change, namely the reform of the Spring and Autumn Period and the Warring States Period. The reforms during the Warring States Period included the reform of the monetary system, the implementation of Legalism, and the strengthening of the central power. Therefore, the answer was as follows: 1. During the Spring and Autumn Period, China experienced a great change, namely the reform of the Spring and Autumn Period and the Warring States Period. 2. During the Warring States Period, the reform included the reform of the monetary system, the implementation of Legalism, the strengthening of the central power, etc. 3. During the Warring States Period, the vassal states began to expand and invade neighboring countries.

According to Material 1, the Spring and Autumn Period was a period where the vassal states fought for hegemony and each country tried to strengthen themselves through reforms. During this period, there was a conflict between the Xia (referring to the middle and lower reaches of the Yellow River) and the Yi (referring to the ethnic minorities such as Rong Di and Di Yi). In order to achieve national unity and strength, the vassal states of the Spring and Autumn Period had carried out reforms to implement "rites and music" to govern the country, strengthen military management, and promote the political status of the "Spring and Autumn Five Tyrants" to engage in diplomatic struggles. These reform measures laid the foundation for the Warring States Period in Chinese history. Therefore, this material reflected the background and significance of the reform of the vassal states in the Spring and Autumn Period, as well as the changes in China's politics, culture, military and other aspects.
