The only way to touch people's heart is books written in life.
Dedicated to my wife in the heaven.

This book originally had two authors, I and my wife, and it was our third book. The stories, experiences and executions inside are all exchanged by her consent, support, encouragement and silent effort. Ten years of anti-cancer, she accompanied me for eight years. The last two years, she has suffered cancer too. Her role was interchanged with me and I still couldn't save her. It was the biggest regret and frustration in my life. From caretaker to the caregiver, it is completely another kind of emotion and thinking mode.
