Account Book Under the Old Locust Tree

Grandma passed away mysteriously, and the police hastily ruled it an accident, but... How could an old man with night blindness get up in the dark? Why did she withdraw 140,000 in cash after living a frugal life? Why were the last few pages of the diary torn apart? Full of doubts, I stayed in Chenjiazhuang to investigate the truth, but I discovered a secret that had been hidden for thirty years... A yellowed account book hides the truth of blood and tears; an old locust tree bears witness to conscience and struggle.
