Describe the parallelism of cold

The parallelism sentence describing the cold is as follows:

1, it's really cold. I'm shivering with cold. It is really cold. It's so cold that my nose keeps running. It's really cold, so cold that I dress like a zongzi.

There is thick snow everywhere, the north wind is whistling and the sunshine is dull. The trees were bare, the birds stopped singing, and people hurried on with their heads down. It's too cold!

3. It's getting cold. Birds can hardly be seen under the blue sky. The weather is getting colder. The river in front of the door is covered with a thin layer of ice. It's getting cold, and snowflakes are floating in the sky.

4. Because of snowflakes, the earth in winter is wrapped in silver; Because of the cold, the rivers in winter are frozen thousands of miles; Winter is unforgettable because of the strong wind.

In such cold weather, not only people can't stand it, but also animals and flowers. The birds that used to sing happily in the branches are gone, even the mosquitoes and spiders I hate are gone. The flowers withered and the grass turned yellow. However, only the pines and cypresses on the roadside are still lush, which has injected several times of vitality into this lonely land.

6. The wind in winter is very cold, but it strengthens my bones and muscles; The wind in winter is very strong, but it has honed my will; The wind in winter is hard, but it can make the weak stronger and the strong stronger; The winter wind is gentle, because it contains a love under its harsh face.
