Cheng Yu was stunned at the door of the laboratory. The grille light above her head gave off a hissing cold light. A feeling of confusion suddenly surrounded her. She didn't know whether she should step with her left foot or her right foot. She sat slumped on the chair and saw the women getting urine test sheets one after another, their faces glowing with joy. Some are first-time mothers, and some may be, like her, having their second child. She looked enviously at the woman who looked to be in her early thirties and smiled brightly while holding the pregnancy test form. She thought to herself that she must be a woman from a well-off family, and the second elder in the family must be in good health and be able to help her raise her second child. There are only such women who have no worries about giving birth to a second child.
