Contracting fault liability means that in the process of concluding a contract, one party should bear the liability for damages due to the breach of its obligations based on the principle of good faith and the damage to the trust interests of the other parties. If the other   suffers from the non interest due to the non-establishment or invalidity of the contract due to the establishment and validity of the trust contract, such non interest is the loss of the trust interest.
