Why did Party C write the company as a public rental house?

Party C is an applicant (enterprise) that meets the guarantee standard. According to the Interim Measures of Hefei Municipal People's Government on the Management of Public Rental Housing in Binhu Huiyuan and Metropolitan Tiandi in Baohe District, we know that the lease contract is in quadruplicate, with Party A as the District Housing and Construction Bureau, Party B as the town and community, and Party C as the applicant (enterprise) meeting the security standards. Applicants (enterprises) who rent public rental housing need to provide the signed public rental housing lease contract to the public rental housing property service enterprise and sign the property service contract on site before they can move in. So Party C wrote the company in public rental housing.
