What is red river valley's speed and mood?

Red river valley's speed and mood are sweet memories. According to relevant public information, the song "red river valley" is a folk song circulating in the Red River in the north, which shows that the residents who immigrated to the Red River in the north reclaimed land, built their homes and developed the city, and finally turned the wilderness infested by bison into people's homes. Looking back on the history of people's hard work is also a yearning for a better life.
