What does the woman mean when she says Huashan talks about swords?

The original intention of Huashan's sword theory is to compete in Huashan, which is extended to open competition or academic contention.

Huashan's sword theory comes from Mr. Jin Yong's martial arts novel The Legend of the Condor Heroes.

In Jin Yong's martial arts masterpiece Legend of the Condor Heroes, it is the first time that Huang (East Evil), Ouyang Feng (Du), Duan Zhixing (South Emperor), Hong Qigong (North Beggar) and (Middle) fought fiercely at the top of Huashan Mountain for seven days and seven nights for the "Nine Yin Zhen Classics". In the end, Wang Zhongyang defeated four people and won.

Huashan's sword theory comes from Jin Yong's martial arts novel "The Legend of the Condor Heroes", which was originally intended to compete in Huashan and extended to an open competition or academic debate. The reason why Huashan Lun Jian is called "Lun Jian" is actually just an elegant name, which refers to all martial arts. The reason why sword is used to refer to all martial arts is because of its special position in weapons. In ancient times, the sword was the king of soldiers and was called "the king of hundreds of battles".
