"What hurtful news for all the parents out there! These days Xingxing's mother (referring to Zhang Ziyi) is worried constantly about her health. Where was the monitoring when it came to vaccination safety? The authorities must investigate the where these illegal vaccines go and severely punish those responsible. I hope Xingxing and all children who are receiving vaccinations can grow up healthily, and I pay my respects to the doctors and nurses who are busy working at children's hospitals!"
