There is a Canglang River flowing in Chang'an City. Whenever Cen Qing goes to Shugui Temple to add a handful of loess to the tomb, he always stops for a moment by the river and listens to them singing:
"The water in Canglang is clear, so I can wash my tassel; the water in Canglang is turbid, so I can wash my feet."
So Song Yilan laughed at her for being crazy.
She stood by the river, with heavy snow falling all around, but the Canglang River under her feet was flowing continuously, and there was never any sign of freezing. She looked at the snow-white crabapple on his fingertips, and asked: "Where can there be blooming crabapples in such a severe winter?"
He picked up the flowers and smiled, "God is kind, so he left a prosperous begonia tree in my garden."
Cen Qing remained silent for a long time. He raised his eyes slightly and touched the sky sprinkled with catkins and salt. She thought of the lonely tomb in the back hill of Shugui Temple, but she couldn't remember whether the begonia she gently placed in front of the tombstone was as bright as ever.
What's going on?
If the sky has feelings, it will also grow old, but the heaven and earth are eternal, the rivers flow forever, and the sky... Has never been old.
