Fortunately, the agreed non-refund conditions are unreasonable, and the conclusion of the contract is not the true intention of the parties, so the legal effect of the contract is reduced, and the party providing the standard clause is exempted from its responsibility, aggravating the other party's responsibility and excluding the other party's main rights, and the clause is invalid.
If there is any dispute about the understanding of the standard terms, it shall be interpreted according to the usual understanding. If there are more than two interpretations of the standard terms, an interpretation that is unfavorable to the party providing the standard terms shall be made.
