According to the scar on Niu Niu's foot, it was concluded at a glance that the murder weapon was these new shoes. It's normal for new shoes to rub, but it's not that serious. Looking at Niu Niu's foot, her parents were in pain, but fortunately the other foot was not scratched.
Finally, Niu Niu's parents sent a complaint letter to the local manufacturer, and the manufacturer also apologized, and explained the reasons for the follow-up inspection, demanding that Niu Niu's shoes be taken back for investigation.
Niu Niu's second birthday was supposed to be a happy day, but it was ruined by a pair of new shoes. I hope Niu Niu will not be adversely affected by this new pair of shoes.
