If you drive by car, you can go directly to Xuanzhou Ancient Town and see Dayuandu Shiplock, which has the same design as the Three Gorges. Then you can eat fish across the river and see the schedule. You can also eat fish first and then see the release of the Shiplock when you come back. Then go back to Hengshan county. You can visit Mao Zejian Martyrs Cemetery when you enter Hengshan County, and then take a walk in Nanyue. Finally, you can eat blood duck at Jiuguanqiao and take a boat to the reservoir. If it is summer, you can swim in the reservoir. You can take you to the reservoir with the boatman. Go home after dinner.
This is what I think is the most classic day in Hengyang, go on road trip. Every time my relatives from other places come, I will show them around like this.
If you don't have enough time, go directly to Jiuguanqiao to eat blood duck and go swimming in the reservoir.
