If you want to prove whether Bruce Lee is a hero, you don't need to look at his fist strength, leg strength and other data indicators, because the data may be ignored because of his age (even what Li Xiangning said may not be accurate, after all, Bruce Lee was only 4 years old when he died).
Bruce Lee's greatest achievement lies in his martial arts concept, his promotion of China culture and China Kung Fu, and his influence in the world. I suggest you prove it to the teacher from these aspects.

Major achievements
Jeet Kune Do: 1967, Bruce Lee founded Jeet Kune Do, a world-class "scientific street fighting" of modern China Kung Fu, at the age of 27.
Bruce Lee Jeet Kune Do poster Jeet Kune Do is an all-round free fighting technique created by Bruce Lee, which combines the essence of all kinds of martial arts in the world. "Jeet Kune Do" refers to the way to stop an opponent from punching, or the way to intercept an opponent's punching. Jeet Kune do advocates a high degree of freedom and instinct in fighting, abandons traditional forms and faithfully expresses itself. It is the program and essence of Jeet Kune Do that "the impossible is the law and the infinite is the limit". It applies the philosophy of the East and the West to Wushu, which is a kind of fighting guidance and methodology. Bruce Lee has its own fighting system, which is called "Bruce Lee Jeet Kune Do" or "Primitive Jeet Kune Do". It is an important part of Jeet Kune Do, but not all of it. Jeet Kune Do is infinitely developed. Jeet Kune Do is a natural weapon to exercise the human body.
Save Boxing: Bruce Lee's save boxing evolved from Wing Chun's "Long Bridge Force", which is a particularly advanced technique in Jeet Kune Do. Bruce Lee's "Cunquan" can hit people who weigh more than 75 kilograms several meters away.
Wing Chun Boxing has a special way of exerting strength, which is called inch strength. The so-called "inch strength" refers to the short and flat explosive force that suddenly accelerates muscle contraction when it is close to the target or when the action is about to be completed. In the wing gate, the wing master can launch a sustained and compact attack without gaining momentum, knocking down opponents at a distance of 1 to 3 inches or even in a close-fitting state.
According to the principle of mechanics, the force generated by the acceleration of an object is the largest. Therefore, if the fist is strong, it must be forced after bending the arm to ensure that there is enough distance to accelerate. An inch of strength is the opposite, requiring a large force in the shortest distance.
Nunchakus: During his stay in the United States, Bruce Lee exchanged nunchakus and fibrin short sticks with dan inosanto, an American Filipino stick master who is also a disciple and friend, and became an expert in using sticks. Bruce Lee used nunchakus for the first time in the Hollywood movie The Green Hornet.
Nunchakus are two cylindrical hardwoods connected by a chain or a thong. They can be punched and strangled, combining the rigidity of the stick with the softness of the whip. An American martial arts monograph once said: "When you wave one end of a nunchaku, you can generate 1.600 pounds of power, which is amazing.
Once the chain or pimp connecting nunchakus is wrapped around the opponent's neck, a light pull is enough to hang a person. Now many states in the United States have passed laws prohibiting the use and possession of nunchakus. The reason is that some young Americans have seen Bruce Lee's Kung Fu movies, or heard of the power of nunchakus, and played nunchakus, which resulted in death and was condemned by public opinion.
"Jingwumen" made the Hong Kong audience at that time see Bruce Lee's exquisite nunchakus, which was amazing. When the Raptors crossed the river, Bruce Lee's nunchakus became two pairs, which made the performance extremely difficult and even more dazzling.
