1.留置权的实现是指留置权人对留置财产进行处分，以优先受偿其债权的行为。

1. The realization of lien refers to the action of the lien holder to dispose of the retained property in order to obtain the priority of repayment of its creditor's rights.

2.根据规定，留置权人实现留置权必须具备两个条件：

2. According to the regulations, the lien holder must meet two conditions to realize the lien:

（一）留置权人须给予债务人以履行债务的宽限期。 债权已届清偿期债务人仍不履行债务，留置权人并不能立即实现留置权，而必须经过一定的期间后才能实现留置权。这个一定的期间，称为宽限期。宽限期限多长，涉及债权人与债务人利益的平衡问题。期限过长，不利于留置权人实现债权；期限过短，不利于债务人筹集资金，履行义务。为此，根据实践经验和公平原则，留置权人与债务人应当约定留置财产后的债务履行期间；没有约定或者约定不明确的，留置权人应当给债务人两个月以上履行债务的期间，但鲜活易腐等不易保管的动产除外。即留置权人留置财产后，便可以与债务人自由协商一定的债务履行期限。如果留置权人与债务人对于宽限期限没有约定或者约定不明确的，留置权人可自行确定宽限期限，但不得少于两个月，除非留置财产为鲜活易腐等不易保管的动产，如海鲜、水果、蔬菜。这些动产保管成本过高，如果期限过长，容易贬值甚至失去价值，对留置权人和债务人都不利。因此，留置权人无须给予债务人两个月以上的宽限期。

（1） The lien holder must give the debtor a grace period to perform the debt. If the debtor still fails to perform the debt after the creditor's rights have reached the repayment period, the lien holder can not immediately realize the lien, but can only realize the lien after a certain period of time. This certain period is called grace period. How long the grace period is involves the balance of interests between creditors and debtors. The term is too long, which is not conducive to the realization of creditor's rights by the lien holder; The term is too short, which is unfavorable for the debtor to raise funds and perform its obligations. Therefore, according to practical experience and the principle of fairness, the lien holder and the debtor should agree on the period of debt performance after the property is retained; If there is no agreement or the agreement is not clear, the lien holder shall give the debtor a period of more than two months to perform the debt, except for the movable property that is not easy to keep, such as fresh and perishable. That is, the lien holder can freely negotiate with the debtor for a certain period of debt performance after retaining the property. If the lien holder and the debtor have no agreement on the grace period or the agreement is not clear, the lien holder can determine the grace period by itself, but not less than two months, unless the lien property is fresh, perishable and other movable property that is not easy to keep, such as seafood, fruit, vegetables. The cost of keeping these movable property is too high. If the term is too long, it is easy to depreciate or even lose its value, which is detrimental to both the lien holder and the debtor. Therefore, the lien holder need not give the debtor a grace period of more than two months.

（二）债务人于宽限期内仍不履行义务。 债务人在宽限期内履行了义务，留置权归于消灭，留置权人当然不能再实现留置权。如果债务人仍不履行义务，留置权人便可以按法律规定的方法实现留置权。

（2） The debtor still fails to perform its obligations within the grace period. The debtor has performed its obligations within the grace period, and the lien is extinguished, and the lienee can no longer realize the lien. If the debtor still fails to perform its obligations, the lien holder can realize the lien in the way prescribed by law.
