The reason for this is the following：

1. This army pays special attention to cavalry, except Ma Jiajun.

2. Ma Bufang's son is called Ma Jiyuan. In the film, Han Jiajun is called Han Jiyuan.

3. The Luoxi column of the Red Army was completely annihilated. Only a handful of the Red Army were wiped out in the history, including Ma Jiajun's marked army in Gao Tai (Wanfotai).

Ma Jiajun was a local warlord who actually controlled Gansu, Ningxia and Qinghai in China during the Republic of China. They are basically linked by family, blood relationship and religion. They started in rough times, prospered in troubled times and formed alliances with various forces. They once occupied all of Gansu, Qinghai and Ningxia, most of Xinjiang, almost controlled the whole northwest, and changed the historical process of China to a certain extent.

Ma Jiajun's main figures are Ma Bufang, Ma, Ma Hongkui and Ma Hongbin, collectively known as the "Northwest Four Horses". Both the Beiyang government and the later national government can maintain their ruling power in the northwest on the premise of recognizing the central government.

At the same time, they also eliminated other forces that tried to damage their dominant position, such as the Japanese army during the Anti-Japanese War and the Japanese puppet government in China. And actively anti-Communist, was eliminated by the China People's Liberation Army, ending the history of Ma Jiajun for nearly a hundred years.

The main figures in Ma Jiajun are Hui, Han, Salar or Tibetan, who believe in Islam.
