What is the charging standard of property fees: 20 17?

I guess, just for reference: 1. Because the developer must be the first to sign a property service contract with the property service enterprise, the dismissed property service enterprise can claim the relativity of the contract and that the owners' meeting has no right to dismiss except the developer. 2. Because the developer must sign the realty service contract with the realty service enterprise first, and the realty service contract is actually completed jointly by the developer and the realty service enterprise, it is difficult to ensure that they have no malicious collusion to harm the interests of the owners. Therefore, before the implementation of the Property Law, there may be many obstacles if the owners' meeting dismisses the property service enterprise according to the property service contract, so there is this provision in the Property Law. Through the provisions of the property law, we can see that the purpose of public power is to fairly interfere with the freedom of contract, and we can also feel a little taste of economic law.
