Memorial on Ten Thoughts for Emperor Taizong

For example, if a country wants to be stable, the monarch must accumulate virtue and justice. Moreover, the monarch must be prepared for danger in times of peace and cannot indulge himself just because he is in a high position. I also like a sentence in it: "It's not about big complaints, it's about people; it's better to be cautious when the boat is overturned." This sentence really makes sense, just like when we live our lives, we can't ignore small problems and treat every detail carefully. The ideas in this book are also very inspiring to our lives!
