"Zhou Hao's grandmother, please calm down," the principal announced, "the police station has conducted a thorough investigation in coordination with our school, and it's been confirmed that the children were poisoned by spoiled egg cakes and double ninth cakes..."
Upon hearing the results announced by the principal, Ma Sufen and Shen Baolan, the mother-in-law and daughter-in-law, were dumbfounded on the spot.
"Impossible! Absolutely impossible!"
Frantic, Ma Sufen hopped up and down. "Our whole family ate those egg cakes and double ninth cakes this morning, and none of us got sick. How could the children get sick from them? You must have made a mistake!"
Shen Baolan quickly chimed in, "Yeah, you must be mistaken. We eat those egg cakes and double ninth cakes every day and never had a problem."
But the parents were furious to the point of explosion.
