Sigu Swordsmanship's mnemonic chant was " to look ahead and ignore the back, to look left and ignore right."
Sigu Jian's Sigu was referring to the front and left side of the battle and not the back and right side.
The reason why Sigu Jian was called Sigu Jian was because the sword technique he created was called Sigu Jian. This kind of sword style was unique in that it cared about the front and the left, which meant that in battle, he only cared about the front and the left, and did not care about the back and the right. The name of this sword technique also represented his sword intent and combat style. Although Sigu Jian was very powerful, he was ultimately crippled by the Qing Emperor's schemes. His end was very miserable.

The reason why Sigu Jian was called " Sigu Jian " was because his sword style and footwork contained the characteristic of " looking forward and not behind, looking left and not right." This kind of footwork allowed him to flexibly respond to attacks from all directions in battle, so he was called Sigu Jian. At the same time, Sigu Jian's swordsmanship also reflected his grandmaster realm." With one glance, he could topple a city. Then, he could topple a country. Three times, he would trouble the world. He would draw his sword and Sigu's heart would be at a loss."
