The question posed by Liu Jinghui rendered Jiang Yuan silent.
Honestly, the presence of art pieces in the cow farm didn't seem like an issue to Jiang Yuan. To be blunt, if Jiang Fuzhen suddenly had a whim and impulsively bought some art pieces to place in the cow farm, it wouldn't be surprising at all.
But from another perspective, even if Jiang Fuzhen would put art pieces in the cow farm, it would be because he enjoys spending time there, not because he has a cow farm where art pieces are placed.
How could a cow farm owner who genuinely appreciates art possibly place Zhang Daqian's paintings in such an unsuitable environment like a cow farm? Not to mention the difficulty of controlling both temperature and humidity, the environment of a cow farm is simply not suitable for appreciating paintings and calligraphy.
However, Jiang Yuan hadn't considered these issues before. His approach to solving cases is technical and, in a certain sense, rather reckless.
