During the quarantine period, I failed to deliver the shop on time and canceled the business license. The landlord wants to deduct my deposit. Is it legal?

It is illegal to query based on relevant information. According to Article 703 of the People's Republic of China and the Civil Code, a lease contract is a contract in which the lessor delivers the leased property to the lessee for use and income, and the lessee pays rent; and the People's Republic of China and the National Code of Article 721 of the Code stipulates that the lessee shall pay rent according to the agreed period. Article 5 of the Supreme People's Court's "Guiding Opinions on the Proper Trial of Certain Issues Involving the COVID-19 Epidemic in accordance with the Law (2)" stipulates that if the leased house is used for business, the epidemic or epidemic prevention and control measures cause difficulties in the lessee's capital turnover or significant operating income If the lessor requests to terminate the lease contract on the grounds that the lessee failed to pay the rent within the agreed period, and the lessee bears the liability for breach of contract, the People's Court will not support it. Therefore, during the quarantine period, it is illegal for the landlord to withhold the deposit if the shop is not delivered on time and the business license is cancelled.
