On June 6, 2022, the public security department of Tianjin issued a circular on the new scam of Tianjin loan sales company, which clearly stated that receiving return calls for local loans in Tianjin is one of the types of fraud activities and belongs to illegal and criminal activities, so it is not reliable.

"Borrowing and returning the phone" refers to that after an individual borrows a loan from a bank, the personnel organized by a professional team answer the phone of the bank, so as to find out the real information of the parties and carry out illegal and criminal activities.
