Use three idioms and a poem to describe the snow in winter.

In this cold season, snow is essential. There is a slight light in the sky, only a little wind holds the snow like a kite. This silk wind dominates the butterfly-like snowflakes, which fall obliquely, fly around in a whirl, float to the ground and fall on pedestrians. People can't help but think of Xie Daowen's Ode to Snow. "The air difference of salting can be simulated, but catkins are not because of the wind." After the snow, the world is decorated with continuous white snow, with lush foliage and jade. This is a gratifying scene of heavy snow.
