April is the best, March is still the melting period, and the scenic spot may not be open. Peach blossoms have been flooding for a long time, about half a month. There is a lot of water in April and May. My hometown is near the hukou. I suggest you go to Hukou, Yichuan, Yan 'an, Shaanxi. Although Hukou Waterfall is the dividing line between Jixian and Yichuan, you can see it on both sides, but when you go, you will find that the waterfall is horizontal, which is a very vivid metaphor. If Hukou Waterfall is compared to a girl, what you see in Yichuan is the front, while what you see in Jixian is the side and the back. Yichuan Waterfall Scenic Area, you can also see Sleeping Girl Peak (the legendary Dayu's wife). There is a Yellow River Bridge at the mouth of the lake. You can choose better.
