Introduction to Baodu Bridge: Legend has it that this is the place where Ma Wu, the general of Emperor Guangwu of the Eastern Han Dynasty, carried a calf across the river when he was a child. Later, after Ma Wu became the founding general of the Eastern Han Dynasty, he returned to his hometown and built this small bridge for his people. In order to commemorate him, people named the bridge Baodu Bridge, and named the pools and waterfalls under the bridge Jiangjuntan and Jiangjuntan Waterfall.
