Why do the weeping willows by the lake hang down to the lake?

Every plant has its own growth characteristics. Weeping willows are named after drooping paper.

For example, poplars only know that when they rush to the sky, the branches of locust trees look like African claws.

Where weeping willows grow, the branches will droop. It's just that it's a water tree, so it's usually planted by the lake.
