The princess of Beiliang was Princess Xingping, the daughter of Juqu Mengxun.

The name of the Northern Liang Princess was Princess Xingping.
Beiliang and Beimang were enemies. Northern Liang was the fief of a king with a different surname in the Liyang Dynasty. It was relatively independent, but it still belonged to the Liyang Dynasty in name. The Northern Mang was the enemy of the Liyang Dynasty and had been attacking the Northern Liang. According to the ending of << The Sword Snow Stride >>, the Northern Liang won and defeated the Northern Mang army.
The ginger paste was called the Northern Liang Princess Consort in chapter 317 of the Sword Snow Stride ". In that chapter, Ginger climbed up the city wall and placed the purple sandalwood sword case under the war drum. When the Northern Liang veteran saw the Great Liang Dragon Sparrow on Ginger, he excitedly shouted the title of Northern Liang Princess Consort.
The meeting of the Snowy Dragon Cavalry with the Princess Consort of Beiliang was in chapter 277 of the novel " In this chapter, Xu Fengnian led the Great Snow Dragon Cavalry to West Chu. When they saw Jiang Ni holding the Great Liang Dragon Sparrow, they all shouted for the Northern Liang Princess Consort. The Northern Liang army only recognized the Great Liang Dragon Sparrow, and only those who possessed the Great Liang Dragon Sparrow were recognized as the Northern Liang Princess Consort. Therefore, when the ginger mud appeared in front of the Snowy Dragon Cavalry, they all knelt down and greeted the Northern Liang Princess Consort.
Northern Liang had lost a large number of soldiers in the two Great Wars of Liangmang. In the first Great Battle of Liang Mang, the Northern Liang defeated the Northern Mang with an absolute disadvantage in numbers, but the price they paid was huge. It was reported that the border troops of the three states of Beiliang had lost more than 100,000 men, while the Northern Mang had lost 350,000 men. In the second Great Battle of Liangmang, there was no mention of the general losses. However, it could be seen that Beiliang had fought to the death in Youzhou, Liuzhou, Liangzhou and other places, and many soldiers had died in the battles. In short, the Northern Liang had paid a huge price in the two Great Wars of the Liang Mang, but they had successfully resisted the invasion of the Northern Mang.
The ginger paste was the Northern Liang Princess Consort recognized by the Great Snow Dragon Knights. In Sword Snow Stride when the Snowy Dragon Cavalry saw the Ginger Mud holding the Great Liang Dragon Sparrow, they shouted 'Northern Liang Princess Consort' and this was their recognition of the Ginger Mud's identity. Mud Ginger had cheered for the Northern Liang in the Great Battle of Liangmang and had received the recognition of 300,000 Northern Liang Steel Cavalry. Even though the ginger mud did not officially become a princess, but she had the Great Liang Dragon Sparrow, this made the Northern Liang cavalry see her as the true Northern Liang Princess Consort. In the end, Jiang Ni and Xu Fengnian lived in seclusion in Jianghu and became lovers.
