Goose comes back to imitate the first paragraph of the text.

When the first red flower blooms, summer may not necessarily come. But when the first cry of Xia Chan pierced the hot air, summer came.

If a flower blooms in the sun, but it is not right, it can also close its petals. The first mosquito broke out of its cocoon and found it was wrong. It can also find a hidden place to continue sleeping. But Xia Chan has been waiting in the mud, waiting for the only chance to see the sun in his life. Once it thinks it's summer, it crawls out of the soil. It's not that easy to go back in.
