It's really hot in the summer, and by 8 a.m. there were already quite a few people there. Climbing up Yueyang Tower and looking out, I saw that the water of Dongting Lake was quite murky. The "green snail" on Junshan Mountain was actually flat. I really admire the imagination of the ancients.
Those who don't want to retrace their steps can exit through the North Gate, but the location shown on Gaode is different from the actual location. The North Gate is now located "by the lake," requiring you to "walk down the mountain," exit the gate, and then "walk up the mountain" to reach the roadside.
