A handed down navy blue cheongsam, the color is like the sea in the middle of the night, and the silence contains endless past events and secrets. Su Ling brought a new navy blue cheongsam and invited him to be the first "reader". She pointed to the pattern on the hem of the cheongsam: "This is the 'ice plum pattern'. Plum blossoms grow out of cracks in the ice. My father said that the fate of our generation is probably like this." Shen Xubai ran his fingers over the pattern: "Then I will be the soil under the plum blossoms, the roots in the cracks." What he gave in return was a special "scale ruler", made of copper, hollow, with a microfilm hidden at one end. There were scales on it, but based on the date when the two met. These love words and this token will become the password and pain throughout life.
