It is understood that the vice mayor and the director of the Municipal Public Security Bureau, Wu Gang, opened the director's mailbox and communicated with the police through the mailbox of the director.

In December 18th last year, the director's mailbox reflected the problem of women's traffic policemen standing guard against freezing, causing Wu Gang's concern, and instructing relevant departments to issue electric heating cotton shoes for female traffic policemen.

Women's squadron policemen wearing electric heating cotton shoes have indicated that they should make persistent efforts in the future work without negative leadership and great expectations.
