Li Bai (AD 70 1-762) was not only a famous poet in the Tang Dynasty, but also proficient in fencing. His life has always been "the sword never leaves the body, and the body never leaves the sword." Xuanhe Shupu once said that he "knew all the books at the age of five, was good at fencing, and was unrestrained." He studied fencing with his father Li Ke since he was a child, and he was able to practice fencing at the age of fifteen. According to Answer Weng in May, at the age of 35, he "learned fencing and came to Shandong". Li Bai is often "drawing the sword and frosting the moon, the night sky." Li Bai is more romantic if he is drunk or emotional. "Sword dancing, all four look askance"; Once drunk, Li Bai is "drunk enough to take off his sword, and the traveler sleeps in the high hall", and nothing matters. ? The sword represents the poet's spirit and ideal, and entrusts the poet's ambition. A long sword and a glass of wine, men put an inch of heart. This is Li Bai's understanding of sword. Therefore, his desire to win glory for the country like Lu Zhonglian, Zhuge Liang and Xie An is often reflected by the sword. "Otherwise, the sword will be brushed and the desert will get great honor." Similarly, when he encounters bumps or twists and turns on the road of life, he often uses swords to express his depressed mood. For example, when Li Bai was in a state of extreme pain and depression, he recited "Abstaining from drinking and falling a muscle, you can't eat, I pulled out my dagger, and I peeped at the road for nothing"; "Play the sword song" Bitter Cold ",before the wind blows"; "Who cares about solitary swords and laments self-pity?" When expressing his hatred for the treacherous court official in the DPRK and his chilling feeling for politics, Li Bai wrote: "The Yanling holds high the Emperor Wu of the Han Dynasty, why does a long sword stand on the jade ladder?" . Reaching is not expensive enough, and poverty is not sad enough.
