Shen Yuanru, the third generation descendant of the Shen family, was originally a scholar who only wanted to preserve the family craftsmanship and these fragile papers during the war. On the way to the west with his family and his family, he met passionate students who wanted to join the army, escorts who escorted the cultural relics of the Forbidden City southward, and folk painters who made a living by forging paintings but had integrity. And the "Painting Garden Secret Treasures" is not only a restoration guide, but also contains a set of mental methods of "recognizing people by observing paintings" - Shen Yuanru relied on this mental method to see through traps and identify loyalties and traitors again and again on the way to escape. On the edge of life and death, Shen Yuanru gradually understood: protecting these papers means protecting the aesthetics, integrity and roots of the Chinese people. This is a war without smoke. Their enemies are war, moisture, mildew, and human greed.
