Legal analysis: if both parties to the contract have an agreement on liquidated damages, it shall be handled according to the contract. The contract law requires the parties to agree that one party shall pay a certain amount of liquidated damages to the other party according to the breach of contract, and may also agree on the calculation method of the amount of compensation for losses caused by breach of contract. If the agreed liquidated damages are lower than the losses caused, the parties may request the people's court or an arbitration institution to increase them. If the liquidated damages are too high, the parties may request the people's court or arbitration institution to reduce them appropriately. If the parties concerned pay liquidated damages for delayed performance, the breaching party shall also perform the debt after paying the liquidated damages.
