This catchword can also be interpreted as the growth and change of human beings. With the passage of time, everyone has experienced all kinds of experiences and setbacks, and is no longer his former self. In the process of growing up, we need to constantly reflect and adjust ourselves in order to better adapt to social changes and requirements.
"Brother is not the brother of the past" also means to see the past experiences and achievements, but not to be too addicted to the past. We need to keep advancing and growing to create a better future. People's life is constantly moving forward, and only by moving forward can we create a better way of life. So, let's keep this sentence in mind, make continuous progress and make ourselves better.
