Why does the Xuyi Urban Management Bureau not use regular closed-type muck trucks?

Netizen "cross-country e-tribe": Hello! You posted on "Sunshine Discipline Inspection" to reflect on the issue of why the dregs and construction waste in Xuyi County are not transported by vehicles with formal qualifications for dregs transportation units. We have instructed the county urban management bureau to conduct an investigation and now reply to the relevant situation as follows: After understanding , Xuyi County Urban Management Bureau has carried out registration and management of companies and individuals engaged in slag transportation in accordance with the spirit of relevant provincial and municipal documents. In the slag management, it has reviewed the qualifications of companies and individuals engaged in slag transportation. In the future, it will be eliminated Companies and individuals with waste transportation qualifications enter the waste market. Thank you for your concern and support for our work.
