Introduction to Yuandang Night: Yuandang Night evolved from the ancient scene "Yuandang Fishing Fire". In the past, the fishing boats in the port returned to the harbor every night and lined up on the shore. On a dark moon night, one boat and one light were reflected in the water, swaying and flickering, flickering in and out, shining in the gravel, and the scenery was wonderful. After the west embankment was built, the fishing fires disappeared; today's "Yandang Night" is dominated by Bailuzhou.
