In the chaotic times of the late Ming Dynasty, the locust trees in Qingyan Town bloomed year after year.
When ten-year-old Su Yao sneaked out of the Su family's deep house, she saw Chen Yu, a boy from the blacksmith shop, chopping open the falling flowers with his sword.
He is the orphan of an actor, a "lower class" who is despised by everyone in the town; she is the jewel of the Su family, who was born to marry the rich man of the Wang family.
But she forced the stolen "Taibai Sword Manual" into his palm: "At three o'clock in the morning, wait for me in the bamboo forest."
He practices swordsmanship while she grinds ink; he forges iron while she adds firewood. Spring cherry blossoms fell over the ends of his hair, and streams flowed over his fingertips. He buried half of his mother's broken hairpin in the soil and carved her name into the most secret lines of the peach wood hairpin.
Until the war drum beats the dream of Jiangnan.
He rode out to avenge his country and promised her ten miles of red makeup; to keep his promise, she was imprisoned in a deep house and survived the rumors and the forced marriage from the Wang family. When he came back with great achievements, she was waiting at the city gate with a handful of old blood-stained purses.
The world said that he died in the snowstorm in northern Xinjiang, and she was the only one holding his posthumous daughter under the peach tree, waiting for the grass to grow on the new grave every year.
Later, she opened an embroidery workshop and a school, tied his sword tassel on her daughter's wrist, and embroidered his name into every inch of the mountains and rivers.
Someone asked her if she was suffering.
She only touched the half-open peach blossom on the window sill and smiled: "He is the brightest light I have ever seen. I am just accompanying him to finish the unfinished half of my life."
Intention: Love is not attached to the momentary heartbeat of life and death, but to live the light of one person into the fire of a group of people in the unpredictable and chaotic world.
