In 1960, due to natural disasters, 3,000 orphans from the south were sent to the Inner Mongolia grasslands and adopted by Mongolian adoptive parents with boundless love. Brother Chaolu, sister Tonggalaga, and Bi Ruoshui and Atenghua, who are of similar age, have different personalities. Some are bold, some are shrewd, and some are gentle. After being adopted by different families, they have different life destinies. After more than 50 years of life experience, some of them have become wealthy businessmen, some have become government officials who care about the grasslands, some are kind-hearted and practice medicine to save people, and some have experienced the ups and downs from iron rice bowls to re-employment after being laid off, but they have all taken root in the grasslands, worthy of the upbringing of their adoptive parents and their own lives.
