Many times, people participate in the course of history unconsciously, creating significant historical events.
Many times, great changes happen right beside you. Without you realizing it, history takes a significant step forward. When you suddenly look back, you profoundly realize your ignorance and powerlessness.
People can only feel the vibration caused by the footsteps of history touching the ground.
For the long span of history, each forward step requires years, decades, or even centuries. But it only takes a day or two for its footsteps to make people tremble.
These one or two days don't really change anything.
They just serve as traces of change, engraved in the river of history, turning into deep footprints for posterity to look back on.
