What does the boundary line mean? In life, we often hear this word. Simply put, the boundary line is a kind of boundary or boundary that people can perceive. This limit is usually the highest level that a person can achieve in a certain aspect. When we reach this state, we will find that we have crossed the border and entered a new state.

Boundary exists not only in the process of personal growth and development, but also in the process of social development. The development of human society, from primitive society to modern society, is constantly advancing in the process of constantly crossing the border line. Every time we cross the border, it is a leap of human civilization and will bring new development opportunities to human society.

The existence of the boundary line has brought us enlightenment. First of all, we should face up to our limitations, always keep an enterprising attitude and constantly break our boundaries. Secondly, we should keep a keen sense of the unknown and the future, constantly pay attention to the development and changes of society, walk in the forefront of the times, dare to cross the border and make contributions to the progress of mankind.
