Global History is an epic spanning thousands of years, revealing the patterns and challenges of human civilization through detailed historical narratives. For modern people, this work is not only  of the past but also  for the future. Issues mentioned in the book, such as globalization, civilizational exchange, sustainable development, technology ethics, cultural diversity, war and peace, economic and social balance, historical periodicity, and education and knowledge transmission, are all closely related to modern society.

Firstly, globalization is an irreversible trend. The book points out that human social development is global, and no country or civilization can exist in isolation. This means that modern people need to adopt a more open attitude toward globalization, actively participate in international cooperation, and jointly address global issues.

Secondly, the progress of civilization stems from the exchange and fusion of different cultures. The book emphasizes that every culture is a crystallization of human wisdom and deserves respect and protection. This implies that cultural diversity is a shared wealth of humanity, and exchanges between civilizations can promote innovation and understanding.

In addition, sustainable development is one of the greatest challenges facing humanity. The book mentions that environmental destruction is one of the greatest challenges in human history. This means that we must take action to promote green development and achieve harmony between humans and nature.

Finally, the periodicity of history reminds us that humans need to constantly reflect and progress. The book points out that the rise and fall of civilizations often result from internal contradictions and external pressures. This implies that modern society needs to be vigilant about internal inequality and external competition, maintaining social stability and harmony.

In conclusion, Global History is a classic work worth deep reflection for modern people. Through its exploration of globalization, civilizational exchange, sustainable development, technology ethics, cultural diversity, war and peace, economic and social balance, historical periodicity, and education and knowledge transmission, it provides modern people with important insights to address future challenges. Let us draw wisdom from history and work together to create a better world.
