There's a reason Su Banxia starts planting vegetables in this section and it's not just plot filler. Vegetables are about patience, about putting something in the ground and waiting for it to grow, about tending to something that can't be rushed. This is literally what her life has been missing—she was gambling, being impulsive, destroying things. Now she's digging holes, placing seedlings at equal intervals, watering them. The image of her planting 'like soldiers' is not accidental. She's bringing order to chaos, which is exactly what her life needs.
The blisters are another symbol that won't let me go. They're the physical mark of her labor, the evidence that she's actually doing something with her hands instead of burning money at a gambling table. But they're also vulnerable—burst, raw, needing care. When Jiang Guo'an applies gentian violet, he's literally treating her wounds. The hands that used to hold cards now hold seedlings and get blisters. That transformation is the whole theme of the book compressed into one image.
The closed door is a recurring symbol too. Her room door stays closed. His room door slams shut. They're living under the same roof but separated by wood and distance. And yet—the lunchbox appears on the table anyway. He finds a way across the threshold even when the door won't open.
And then there's the Political Commissar's story about the marriage certificate being slapped on the table. That moment—public, defiant, almost aggressive—contrasts so sharply with Su Banxia's current performance of humility. She's now the one taking responsibility, defending him, saying it was all her fault. The woman who was once so reckless with their union is now carefully protecting his reputation. The theme here is about how people can change, but also about how hard it is to be seen changing.
