According to Article 106 of the General Principles of the Civil Law, anyone who infringes upon another person's property due to his fault shall be liable for compensation. Article 1 17 stipulates that if the property of the state, the collective or others is damaged, it shall be restored to its original state or compensated at a discount. Discount compensation here generally means that you only compensate for the actual loss. As for whether the actual loss is higher than five times or lower than five times, it depends on the specific appraisal results. But I personally think that if the other party can't prove the rationality of 5 times the demand, you only need to pay 2 times. Five times compensation has no legal basis.

Good luck.
