Autumn is the season of red leaves. The gorgeous red leaves render the autumn atmosphere to the extreme and add a warm color to the city wall ruins of Chang 'an City in the Han Dynasty.

On the last day of October, on a very fine afternoon, I strolled comfortably along the moat. The sun was warm and the breeze blew, allowing the atmosphere of autumn to fill the world.

Hancheng Lake Heritage Park is located in the northwest corner of the ancient city of Xi'an. It was rebuilt on the ruins of the ancient Chang' an City moat. The water area of Seoul Lake is more than 850 acres, which is equivalent to the size of five Xingqing Lakes. The lake surface is more than 7,000 meters long. It looks like a jade belt embedded in the city from the sky.

The iconic landscape of Hancheng Lake in Xi'an-the "Dafeng Pavilion" in the Hancheng Lake Scenic Area. "Dafeng Pavilion" has a main height of 63.3 meters, imitating the Han Dynasty building, which is based on the artistic conception of Liu Bang's "Gale Song":"The strong wind rises and the clouds fly, and the sea returns to my hometown, so that the brave soldiers can guard the four directions." It is the commanding height of the Seoul Lake Water Conservancy Scenic Area and one of the landmark buildings in the scenic area.

Huilan Bridge is another landscape bridge in the Hanqiao Water Town area. On one side of the bridge is a planned commercial pedestrian street, and on the other side is a waterfront landscape leisure area dominated by green landscapes. It is built to make it easier for tourists to travel between the two sides of the lake, enrich the sightseeing routes, and achieve the effect of walking and different scenery. Its shape is tortuous and its winding path leads to the secluded world, just like a sculpture, naturally integrated into the landscape environment.
