Roughly half of all tenancies are based on a unique system known as jeonse, or " key money" .

大约有一半的租约是基于一种独特的系统，称为长期租约，或“关键钱”。

Under a jeonse contract, the tenant pays the landlord a deposit of between 60% and 80% of the purchase price to live rent-free for two years.

根据长期租约，租户需要房东支付购房价格60%至80%的押金，以换取两年的免租金生活。
