When we come into this world, we are destined to meet and separate constantly from the moment we fall to the ground. Some people say that all people are like big fish. I think we are a bird without feet. We have left the ground and kept flying since we broke our shells. Everyone's life is a circle. Some people appear in your life with great fanfare, and then leave silently in the end. Some people slowly become the habit of our lives like air, and finally condense into the most real and profound existence. Destinations come and go, birds fly across the sky without leaving a trace, but the sky has witnessed countless memories. The ancients said that it takes five hundred times to look back in the past life to pass by in this life. For me, all the people I know and all the things I have experienced are just so that I can become what you like at the right time. Today, I am here to write my story.
