Emperor Huizong of Song dreamed of the wonderful realm where "the rain clears and the clouds break, and that is the color of the future," and artisans used agate in the glaze to create the legendary celadon of Ru ware, which is like jade, not jade, yet better than jade. In the inner court, to curry favor with the Emperor's beloved Ru ware, the factions of Noble Consort Hua and Consort Shu vied for favor by having various kilns fire it. Modern researcher Zhang Gongcheng "time-traveled" here by restarting the celadon color to continue writing the legend. Folk rumors say that even with a household fortune of tens of thousands, it does not compare to a single piece of Ru ware, and he embarked on a journey to explore ancient kilns, accidentally uncovering the unknown secret origins between the imperial family and Ru ware.
