How to deal with the conflict between contract terms and management regulations?

Shenyang Property Management Regulations is a local regulation promulgated and implemented by Shenyang Municipal People's Congress (not promulgated by Shenyang Municipal Government, but its legal effect is higher than that promulgated by Shenyang Municipal Government). If the relevant provisions of this regulation do not conflict with the relevant laws and regulations of the state or province, then the contract terms should not conflict with the Shenyang Property Management Regulations from the beginning, otherwise it will be invalid.
