Because Li Yuanhao submitted to him!

When Emperor Renzong saw that the other side had already submitted to him, he decided to give up the war.

Old Fan, Old Han, come back to the Central Committee. I have many things for you to do!

So, this strategy was shelved.

My grandfather's Yongxi Northern Expedition wiped out the nation's elite troops, my father cultivated a formidable enemy for the Song Dynasty, and my son withdrew at the most crucial moment.

The three-man gang that's ruining the country!

By the time of Emperor Shenzong, the Song Dynasty was riddled with problems, and Emperor Shenzong, defying public opinion, insisted on reforming and innovating.

Emperor Renzong reigned for over forty years. After his death, Emperor Yingzong ascended the throne.

Emperor Yingzong was not Emperor Renzong's biological son. In order to establish his authority, the Song Dynasty once again launched a large-scale frontal war against the Tanguts.

But they still lost. They had no geographical advantage, no human support, and only bad timing. They couldn't win this battle.

Moreover, although the Liao state outwardly maintained a peaceful relationship with the Song state, it secretly continued to support the Xia state in order to contain the Song.

In this frustrating situation, Emperor Shenzong, with his strong temper and personality, stepped onto the historical stage and began to pursue his ambitious goals.

From Wang Anshi's reforms of the military in the Northwest to the five-pronged attack on the Xia dynasty, this emperor heard countless voices of opposition every day. Even in his dreams, he could hear Sima Guang shouting: "No! Your Majesty!"

It wasn't until the reign of Emperor Shenzong that the Song Dynasty's strategy towards the Tanguts truly matured.

Why do we say that we've truly matured?

At this time, a truly ruthless person emerged: Wang Shao!

Wang Shao was a poor student who failed the exams many times, so he went to travel in the Northwest.

Some people travel by eating and drinking and then carve "I was here" on stones.

But Wang Shao went on his travels to investigate the terrain, landforms, and culture.

After his inspection, he wrote a letter to Emperor Shenzong entitled "Three Strategies for Pacifying the Rong": "If the country wants to pacify the western bandits, it would be better to first use its authority to subdue the Hehuang people; if it wants to subdue the Hehuang people, it would be better to first use its kindness and trust to win over the border tribes."

This means that if the Song Dynasty wanted to destroy the Dangxiang in the west, it first had to make the Hehuang submit, put military pressure on the Dangxiang from the west, disperse the Dangxiang's troops in the Hengshan area, and surround the Dangxiang from all directions.

This strategy is similar to Zhang Qian's strategy of "severing the right arm of the Xiongnu" during the Western Han Dynasty.
