Is there an unknown interest chain for camphor trees in many communities in Shanghai?

Having worked in the management of high-rise property projects, the owners on the fifth and sixth floors especially want to trim tall trees, because this will affect their lighting. The owners on the first and second floors hope that the property management company will prune the branches clean, because mosquitoes and small animals will run to the owners' homes. As a property, it is actually very helpless. I don't know who to listen to and how to deal with it. According to the law, the felling of trees by property companies must be approved by the urban landscaping department, and it is not allowed to cut trees at will. The premise of this condition is that more than two-thirds of the owners of this building agree. You can consult the government hotline to see if the property has legal procedures and processes, and whether the owner agrees to cut down trees, so as to judge its use. Sometimes, the property management company may have publicized all the owners, but the owners were torn off or damaged before they could read the announcement. It can't be judged that this phenomenon belongs to interest transfer.
