On July 29, in response to a netizen posting that they had eaten a suspected metal crown foreign object in the Luxi River peach cake they ordered on the Sam App, the customer service at the Luxi River Tmall flagship store responded that they had noticed the online information and was being traced back to it. All Luxi River products have gone through multiple quality controls such as metal detection, and can only be marketed if they are qualified from the factory. The store's customer service said that currently they don't sell nut peach cake; nut peach cake is exclusively for Sam's channel.
