The protagonist of the era, in Lu Ping'an's view, is actually always about the "era" rather than the "protagonist."
Although Lu Ping'an could already be called the "protagonist of life," as someone who always upheld a people-centric historical view, he has always valued the era over the individual.
In his eyes, the era is like a tidal wave. When the waves crash onto the shore, there's always a batch of spray that hits the beach first—it could be either you or someone else. To the era itself, there's no difference and it doesn't matter; it's merely the latest wave to leap out.
However, he never denied the "individual's choices" in terms of their impact on the era.
