Chu Yanqiu was calm and self-possessed throughout his life, and only lost control twice: once when he could not find Xue Wenling on the Long March, and once in 1951 when he had to walk with her back.
He is a doctor with a scalpel who vows to strengthen the body of a nation;
She is a messenger who rides the airwaves, determined to awaken voices for New China.
In the flames of the Long March, they were comrades sharing the last piece of dry food;
During the Yan'an years, they were comrades who shared the same oil lamp to refine their ideals.
They never said they were in love, but they got married under the witness of the organization and engraved their vows into their faith.
Until the spring of 1951, two transfer orders arrived at the same time:
He traveled north to the frozen border to defend against invisible germ warfare in a silent place;
She went west to the vast desert and set up a sound communication network in the wind and sand.
From then on, mountains and rivers were covered with letter paper.
He sent a piece of snow from the northern Xinjiang, and she gave him a grain of sand from the western region in return.
The intermittent ticking sound on the radio wave was their only "good night".
Purpose: How personal ideals resonate with the mission of the times
