In the morning, a caravan from the north arrived in Feng City.
The carriages traveled along the main road that runs through this ancient city from south to north, the wheels turning and producing a monotonous sound as they rolled over the bluestone slabs.
Zhao Douan sat inside his own carriage, lifting the curtain to let his gaze sweep across the ancient architecture lining the streets of Feng City—the buildings of the Coastal Marine Road, different from those in the Capital and along the Huai River.
Most of the structures were two-story, with roofs steeper and larger than those in the north, and ditches were dug on both sides of the street to channel rainwater.
The "Great Yu Geographical Record" states that the terrain of the Coastal Marine Road is low, near the East Sea, with Feng City's terrain especially low-lying. Additionally, due to its proximity to a mountain range called "Yunling," it forms a particularly rainy geographical pattern.
