Xia Yong carried the specialty of architectural renderings in the "ruled-line" (jiehua) manner to new heights of technical control. In contrast to his loosely described landscape elements, Xia's buildings are densely detailed and meticulously drawn. This predeliction for minute scale is also evident in the artist's microscopic inscription, which transcribes "A Rhapsody on the Yellow Pavilion," an essay by the famous Northern Song scholar Su Che (1039–1112), the younger brother of the poet Su Shi (1037–1101). Su Che's inscription describes how the region around Xuzhou, in northern Jiangsu, was flooded in 1077, following a sudden break in the dikes of the Yellow River. Su Shi, then a prefect there, worked indefatigably to rescue the city from disaster. After the flood subsided and the city walls were repaired, the Yellow Pavilion was dedicated in his honor. Three centuries later, in 1344, the Yellow River flooded again, causing widespread destruction. By referring to a flood that occurred three centuries earlier—and concealing his real message by writing Su's text in a script so minute that few would actually have read it—Xia Yong obliquely signaled his awareness of the momentous social changes caused by the flood, which would lead to the downfall of the Yuan dynasty less than twenty years later.
