Hakuho won the victory in the New Year Tournament

Yokozuna Hakuho won the victory in the New Year Sumo Tournament. He won 6 victories in a row. Is Hakuhou too strong? Or are the other wrestlers too weak? I don't know.
In the evening, I called my older sister in Fukushima. I asked about our parents and other relatives, because I am now collecting materials to write my personal history. I have recognized that it is very difficult to know about the root of myself. I wanted to know how my parents had spent their lives, but found it very difficult. My father was born in Miyagi prefecture, came to Hokkaido, worked for a paper company in Ebetsu, then, moved to Tokyo to study law in university. My mother was born in Hiroshima, came to Tokyo, and worked for the Ministry of Communication. When and how they married, I don't know. I was adopted by my mother's mother, but I don't know who my adopted father was. I asked my sister about it, but she answered he must have died years before I was adopted. I thought I would have to write my personal history without referring to my ancestors.
