As a buyer, in the process of transferring the Tmall store, if you are worried about the debt problem of the store before the transfer, you can indicate it in the transfer contract, reflecting the agreement on the early debt problem of the Tmall store. For example, the seller promises that the company has no debt, and if there is debt, which party will bear the corresponding terms.
Or the contract indicates that the loan is not allowed after the transfer of the store, but the buyer uses the store loan during the operation period, and which party bears the debt.
