Does the contract signed by the property management and the operator for renting public areas have legal effect?

The public * * * area is owned by all owners, and the property management company has no right to operate the public * * * area without permission. Even if they rent out or do other businesses, all the profits should belong to everyone. This part of the profits should be used for the construction and transformation of the community, used by the owners, and the property management company should not take it for itself. The contract signed between them has no legal effect, because the public part itself does not belong to the property management company, but is managed by the property management company. The premise of leasing is that the owners' committee agrees, or more than 50% of the owners agree.
