Not true.
Ping An Puhui will not require customers to send debt vouchers by adding friends through WeChat. This method is very unsafe. Ping An Puhui will generally use formal channels (such as official website, public account, customer service phone number, etc.) to communicate with customers. If the WeChat message you receive claims to be from Ping An Puhui and requires you to send a debt certificate, it may be fraudulent information.
If you receive a WeChat message that claims to be from Ping An Puhui and requires you to send a debt certificate and apply for exemption or reduction, do not believe it, as it may be a scam.
