Lin Mu, a junior girl, missed elementary school in her junior year, junior high school in her senior year, and high school in her junior year. Along the way, I have always missed yesterday and looked forward to tomorrow, but I have never been able to live well today. Maybe it's because I'm getting older that I always love to reminisce, but more often it's because I'm not satisfied with the current situation. But I always think too much and do too little. Whether it is study, work or the emotional jungle, in the end only the mottled tree shadows and chaos are left.
