One night, the emperor saw in his sleep a mysterious blue shadow through a fissure in the clouds after a downpour. When he woke up, he wrote about the scene in a poem, and instructed his potters to make porcelain of the color as described. Craftsmen all over the country had to scratch their heads for a long time, until the kiln in Nhu Chau sent the first work in the glaze color "Vu too heavenly van van" – Sky after rain (half blue, half-bar slightly pink).
