Legal analysis: if one party fails to perform the debt or the performance of the debt does not conform to the agreement and cannot be enforced according to the nature of the debt, the other party may request it to bear the expenses to be performed by a third party.

If the performance is not in conformity with the agreement, it shall bear the liability for breach of contract in accordance with the agreement of the parties. If the liability for breach of contract is not stipulated or clearly stipulated, the injured party may reasonably choose to ask the other party to bear the liability for breach of contract such as repair, rework, replacement, return, price reduction or remuneration according to the nature of the subject matter and the size of the loss.
