Is it illegal to interrogate Zheng Shandong by telephone?

Not illegal. "Hotline 12345" is a public welfare and comprehensive service platform for Shandong provincial government to receive consumer complaints, reports, consultations, suggestions and inquiries. According to the "Measures for the Administration of Government Service Hotline in Shandong Province", callers should use the hotline according to laws and regulations, and should not reuse the hotline resources and occupy the hotline resources for a long time without justifiable reasons, and should not interfere with the normal operation of the hotline. So it is not illegal to call the government in Shandong.
