When Shi Nianyao heard this, her legs nearly gave way and she almost fell.
She straightened her posture at once as she looked down at them from halfway up the stairs. Shi Xun was looking at Si Jingyu with a puzzled expression and asking, "Mom, what's the matter?"
Si Jingyu replied, "I have no idea where I placed our household registration booklet. I need to get a visa tomorrow and will need the household registration booklet for that."
Shi Xun shook his head and said, "We keep separate household registration booklets, how would I know where you might have placed yours?"
Si Jingyu was mystified. "That's strange. I was quite sure I placed ours in the study. Why has it disappeared?"
Shi Xun immediately said, "Mom, you must remember wrong."
"Not possible. I saw it there a few times."
Shi Xun was puzzled too now and continued, "Where could it have gone?"
