How did the legend of the blue and white snake come from?

The whole poem is: white wall, queen horse head wall, lattice window cloister In the dream, the water town is fragrant and green, and the jade falls to comfort Suzhou and Hangzhou.

Unknown source.

Interpretation: small blue bricks and tiles, horse head wall, carved beams and painted windows, cornices hanging out, cloisters hanging down, beautifully carved, eaves upturned, magnificent. It's like seeing Tang Bohu's landscape paintings in a dream and visiting Suzhou and Hangzhou in person.

Extended data:

Huizhou architecture is mainly centered on deep patio, forming an inward courtyard surrounded by high walls and without tiles outside. Lighting and ventilation can only be obtained through narrow patios.

This patio-centered, high-walled shape is the focus of attention of the majority of users. Rainwater flows into the patio from the roof, which is also called "four waters return to the hall". At the same time, it vividly reflects the mentality of Huizhou merchants that "fat water does not flow outside the field", which is similar to Shanxi architecture.
