Lady Bamboo from the Monster Series

I think that since he was a child, his father did not love his mother, and he will naturally go out on his own early when he grows up. Unexpectedly, my father inherited a strange thing before his death. A bamboo lady, an iron box, and a three-inch little boy. He didn't know what his father had planned, but it was enough to throw his orderly life into chaos! Who is he provoking?
