世界的故事 第一冊【古代篇】：從游牧民族到羅馬皇帝

The book covers a wide range of cultures from nomads to the Roman Empire. I'm curious how the author balanced depth and breadth to keep young readers engaged.

Some periods felt very brief while others got more detail. I wonder if this was to fit the educational scope or to keep the story lively.

There are so many fascinating moments in ancient history—what guided the choices to focus on certain events or civilizations over others?
