李小龙身高体重，一个曾经被广泛讨论的话题，如今早已成为公开的秘密。在官方记载中，李小龙的身高为173厘米，体重64公斤，这一数据并没有给他带来特别的优势，却为他提供了超乎常人的力量。他的中国功夫不仅在国内受到认可，在国际上也获得了无数赞誉，他将除了电影明星头衔之外，还以中国功夫的标签自豪。

作为咏春拳派继承人的李小龙，其师傅是武术界传奇人物叶问。在27岁时，李小龙融合了武术、哲学和学问，将“截拳道”这一自由度极高的武术创造出来。截拳道不仅包含武学招式，更是关于哲学思考，以中国道家思想为基础，再加上西方哲学观念而成。这门武术强调“以无法为有法，以无限为有限”，锻炼的是人类与生俱来的身体武器。

除了截拳道，李小龙还被人们称道的还有“寸拳”和“双截棍”。他的寸拳直接来自咏春中的“长桥发力”，是一种截拳道招牌招式，也是他最喜欢使用的一种武术。在手中挥舞着这门技术，即便是在对手体重达75公斤的情况下，他依然能够用寸拳将其打飞几米远，而自己的体重只有64公斤。

在多部关于他的影视作品中，双截棍也是不可或缺的一个元素。这一种似棍似鞭的武器既拥有棍子的力量，又如同鞭子般灵活，可以同时发挥两者的优点。生活中的李小龍也经常随身携带双截棍作为防身工具。

对于许多人来说，对于是否真实存在的问题，他们相信李小龙确实在实掌握了一定的武艺。尽管为了安全起见，一些危险镜头可能会由替身演员或者利用特技完成，但从拍摄电影中可以看出，所有动作都是由真正参与表演的人员完成，没有使用替代品或机械设备。如果这些动作都是假象，那又何必自己承受这样的挑战呢？

除了电影领域之外，Lee's martial arts achievements also prove that his skills were real. At the age of 27, Lee founded a new fighting technique called Jeet Kune Do, which is a hybrid martial art that combines elements from various martial arts disciplines into a unique and effective fighting style.

Furthermore, there are many records of Lee's fighting data in his personal archives, which have left many people in awe. These records serve as concrete evidence of Lee's actual combat abilities and help to confirm the authenticity of his martial arts skills.

The documentary "How Bruce Lee Changed the World" provides an intimate look at Lee's life and explores how he influenced various fields such as film, music, sports, design, philosophy and more. The documentary showcases how Lee brought ancient Chinese martial arts into modern popular culture and made it an enduring part of contemporary society.

The History Channel produced this documentary because they believe that Bruce Lee was a remarkable figure who helped to globalize traditional Chinese martial arts. His impact on film and martial arts has been widely recognized by audiences worldwide. As an iconic symbol for generations to come, Bruce Lee will continue to be remembered through these documentaries like "How Bruce Lee Changed the World."
