1972, Deep in the mountains of northwest China.
Su Tang is the "medicine pot" that everyone in the village despises. He was born with a heart disease and will not survive until twenty. No one knows that she is the only daughter of a missing officer in the capital, and she has a jade pendant hidden close to her that can change the world.
Lu Yan is a "madman's kind" that is feared by the whole village. He broke off people's fingers at the age of six and his eyes are colder than wild wolves.
No one knew that he had secretly kept herbs, hares and eggs on her windowsill for four years.
She said: "Don't come to me again."
He said: "Okay."
But the next day there were still dry charcoal and a pack of cough medicine on the windowsill.
The whole village said he was crazy.
Only she knew - his hand was very steady, and the force of applying the medicine was so gentle.
Later, the wind stopped and someone came to pick her up in a military jeep.
She turned around and ran towards the figure who was walking towards the mountains: "You have a family too."
