My name is Su Ran. I have worked hard in a bustling city for many years and am very busy trying to make a living. Recently, a letter from my hometown broke my originally peaceful life. The letter was delivered by the old postman in the village. The handwriting was crooked and there was only one sentence written on it: "Ran Wazi, come back soon. Something big happened at home, and it involves your grandfather's secret."
When I saw the words "grandfather's secret", my heart skipped a beat. My grandfather passed away when I was very young. My family has always kept secret about him. We only know that he was once a highly respected elder in the village, but I know nothing about his secrets.
