It reflects that the Hongkou District Health and Health Commission and Hongkou Airport Authority shirked each other and refused the petitioners' letters and visits. I sent the petition to Hongkou District Health and Health Commission by express delivery according to law, but it was rejected. Shanghai Hongkou District Health and Health Commission 250 15470 claimed that Hongkou Airport Authority didn't give it to them, and the responsible security guard refused. "People's Republic of China (PRC) Postal Law" and "People's Republic of China (PRC) Postal Law" only stipulate that official documents of the country must be sent by express mail or registered mail of China Post, but there is no provision for the mailing method of letters and visits. Various departments in Hongkou District maliciously obstructed the people's right to petition and refused to petition. According to the Regulations of Shanghai Municipality on Letters and Visits, the staff of state organs at all levels who violate the provisions of these regulations in the process of handling letters and visits shall be punished by their units or higher authorities, informed criticism. Require the staff of relevant organs to informed criticism according to law. Optimize the way of letters from the masses and administrative organs.
