The old locust trees in Qingwa Lane have witnessed the entire youth of Shen Nianan and Lu Zhiheng.
In the summer of 2008, six-year-old Shen Nian'an used half a piece of mung bean ice to knock open the heart of a silent boy, Lu Zhiheng. In the years that followed, their playfulness and tacit understanding were hidden in the fragrance of the locust flowers - he served as her "meat pad" when she climbed trees, he silently cleaned up the mess after she got into trouble, and he stayed by her bedside when she was sick. But when she was sixteen, Lu Zhiheng said goodbye suddenly, leaving her to spend a long time waiting.
