Is "Regulations on Property Management in Sichuan Province" mandatory or administrative?

The Regulations of Sichuan Province on Property Management is mandatory. According to the relevant information, the so-called administrative compulsory provisions mean that the violation of such norms will lead to the invalidity or invalidity of the contract, and the violation of such norms will continue to perform the contract and will be subject to administrative sanctions by the state, but the contract itself does not harm the interests of the state, the public and the third party, but only undermines the state's norms on the management of transaction order. If the contract continues to be valid after violating such norms, it will not harm the interests of the country or society, but will only harm the norms of the interests of the parties.
