On the first day of the new year, the martial arts movie "The Guardian: The Wind Rises in the Desert" was released in theaters. On February 27, the film's box office exceeded the 1 billion mark, becoming the first martial arts film in Chinese film history to have a box office of more than 1 billion. In the movie, the scene in which Ayuya, played by Chen Lijun, bites off arrow feathers and shoots a curved arrow triggered heated discussions among netizens.

In response to this, the Institute of Physics of the Chinese Academy of Sciences conducted a popular science study and said that this problem seems to come from a film and television segment.But behind it actually involves an aerodynamic issue: the stability and disturbance response of flying objects.

According to the Institute of Physics of the Chinese Academy of Sciences, biting off one side of an arrow's feathers will not only prevent the arrow from bending gracefully, but will instead cause it to fly crookedly, short, or even roll on the spot.

In the movie, biting off one side of the arrow feathers so that the arrow deflects and hits the opponent is an artistic process and is basically impossible to exist in the real world.

It is understood that "The Bodyguard: The Wind Rises in the Desert" is adapted from the hardcore martial arts comic "The Bodyguard" created by Xu Xianzhe. It is directed by Yuan Heping and supervised by Wu Jing. It stars Wu Jing, Nicholas Tse, Chen Lijun, Sun Yizhou, Yu Shi, Ji Sha and Li Yunxiao, with a special performance by Tony Leung Ka Fai and a special friendly appearance by Jet Li.

The film brings together four generations of "the most capable" martial artists, bringing together half of the martial arts world. It not only carries the return of martial arts sentiments, but also demonstrates the continuation of inter-generational inheritance.
