What is the town house oolong rumored in rural areas? According to my mother, there was a town house oolong under the old earthen house. It looked like a snake, tailless and purple.

Last night, I went out to take a bath from my bedroom at ten o'clock. I saw a snake when I turned on the light. It's neither too big nor too small, and its skin has faded three or four times. By the time my mother got up, it had already got into my grain pile. My mother said it was a good snake, called Oolong, and she ignored me. A small snake was found in my house the year before last, only smaller than this one.
