15-Year-old Ren Qiuqiu graduated from junior high school and then studied at a technical school for two more years. She was extremely tired of China's education and joined the craze of working south. She was a small drop in the vast sea. She was ups and downs in the bustling city of Shenzhen. She experienced the most beautiful first love in her life and witnessed countless infatuated men and women. In the hustle and bustle, she chose to leave just because she wanted to preserve her own poor self-esteem.
