门槛
How to Understand
门槛 refers to a physical threshold or step at the entrance of a room or building, often the lowest part of a doorway. It can also be used metaphorically to describe a standard or level that must be met before something can happen.
The character 门 (mén) means 'door' and 槛 (jiàn) originally referred to a wooden frame or ledge around a door. Together, they form a term that literally describes the structural element at a doorway, but it has expanded in meaning to include abstract thresholds.
In daily life, 门槛 is commonly used both literally and figuratively. For example, it might describe the physical step at a door, or it could refer to the minimum requirement for entering a certain group or achieving a goal. It is also used in expressions like 跨过门槛 (to cross the threshold), which can symbolize beginning a new phase in life.
