Huang Pizi Takes Me to Eat and Drink Together

My name is Wuzhuan. Both of my parents died when I was young. There is only one grandpa in the family and I depend on each other. As long as I can remember, I have had a vague feeling that something has been following me, but when I turned around, it was gone. No matter how I looked, I couldn't find it. After I told my grandfather about it, he picked up the pipe in his hand and threw it at me, "You unlucky naughty boy, you are learning nonsense every day." From then on, I still felt that something was following me, and I didn't dare to tell my grandfather. Until one day, I finally saw clearly what was following me. It was a yellow-skinned creature that everyone was afraid of.
