Is it reasonable for all communities in Chengdu to charge opening fees?

Unreasonable. According to the query of the property management system, the property fees paid by the owners include greening fees, elevator use fees, doorman salaries, etc. Opening and closing the door is the basic job of the doorman, so the charge for opening and closing the door in Chengdu community is unreasonable, so you can complain. Chengdu, referred to as Rongcheng and Jincheng for short, is a prefecture-level city, provincial capital, sub-provincial city, megacity and national central city under the jurisdiction of Sichuan Province.
