"If you ask me, what does this book mean to me? It is indeed a great question. This book bears my faith in life. This book records an 8-and-half-year biological process of ‘turning pupa into a butterfly.’  Thanks to the accident, I had been reduced from a caterpillar to a pupa. I was enclosed in my thick cocoon, searching for meaning, searching for a way out, searching for a breakthrough. It was the suffering, struggling, questioning, trying, failing, experimenting, and forgiving, that forged my mind, my body, and my spirit. Many times I thought of giving up. But the universe has a way to cheer me up, again and again, leaving me all the signs to follow. Yes, I followed, I learned, I grew, and I transformed. One day I broke through the cocoon. I can fly. This book becomes my wings that take me further towards my destiny: a decent and useful human being who is here to create, serve, and help."
