Night tour introduction: The moat is beautiful during the day and even more charming at night. Tourists taking a night cruise can see the silhouettes of buildings outlined by lights along the coast reflected in the water, creating a unique style. It is reported that the landscape lighting along the river mostly uses solar lamps, which are environmentally friendly and do not consume electricity. The compact design greatly highlights the unique spring water charm and artistic taste of the night view of the Huancheng River, which can be described as ingenuity.
