According to Netease News, some merchants in Haining Leather City claim to sell real fur products. In the investigation, merchants used lighters to check the authenticity of furs, and claimed that the furs they sold were genuine leather rather than artificial furs. Although there are trademark registration problems and infringement disputes, this does not directly involve the authenticity of the product. Therefore, according to this information, it can be concluded that most of Haining minks are true.
