The two sides of Budapest are beautiful at night, and the Danube River cruise is a great way to explore the soul of Budapest, especially when the night is low, the river is transformed into a flowing picture, bringing the glorious history and romantic atmosphere of both sides of the Straits to the road. We chose to board the boat in the evening, the cruise ship slowly left the pier, the steel skeleton of the chain bridge shining under the light, this ancient bridge built by the Count of Cecchini, not only connects Buda and Pace, but also carries the regret of not doing the filial piety and the oath of crossing the sky. Became the first pearl on the "mother river necklace" in the hearts of Hungary. Between the boat, the ear flowed the melody of the blue Danube dance, as if Strauss' notes were still jumping between the waves, intertwined with the reflection of baroque spires and gothic arch windows on both sides of the river. On the Pace Plain on the east bank, the neo-Gothic-style parliament building is like a dream of gold, and 87 minarets and golden domes are dazzling in the night, and their reflections are rippling with the water, like the temple held by the Danube. The Buda hills in the West Bank are outlined by the outline of the Buda castle, a palace complex that has undergone Mongolian invasion, Turkish occupation and World War II campfires. Now it stands on the mountain as a museum, and the warm yellow lights are plated with softness on the stone walls. The boat crosses the bridge, the obtuse-angled bridge is extended to the middle of the island of Maglit, an oasis-like park looming in the night, with the wings of the pier angel statue skimming across the line of sight. On the deck, we leaned against the bar, and the lens captured the curve of the Elizabeth Bridge, or the emerald steel skeleton of the Free Bridge, and the nine bridges sounded like strings of different styles, playing architectural symphonies on the Danube.
