This is a past story that happened in the Loess Plateau, at the foot of Black Tea Mountain, in a small county town, and in a prominent family named Niu. In the summer vacation of 2013, I followed my father's instructions and went with my brother to attend the funeral of an uncle in my family. I heard that he died suddenly due to a car accident. My father, who was working in the factory, could not take leave at that time, so he had to send my brother and I, two children who were spending the summer at home, to go on his behalf. I originally thought this was just a small episode in the summer, but it disappeared after that. But things in the world are so unpredictable. In addition to attending the funeral, I also followed an elder I had never met before to visit the "Xingxian Caijiaya Revolutionary Memorial Hall" built based on the deeds of several generations of the Niu family. Listening to the old stories recounted by the old man, I admit that I was excited and could not even imagine that I was a descendant of such a once glorious family. At that time, I was eager to record these old events in words. After many delays, I was unable to start. Now I can finally write down.
