Bruce Lee was a student of the great martial arts master Ip. They made two movies about the life of Ip. Well worth watching.

Mr.T  I found this on Wikipedia.  I don't know if it is true.

After a year into his Wing Chun training, most of Yip Man's other students refused to train with Lee after they learnt of his mixed ancestry, as the Chinese were generally against teaching their martial arts techniques to non-Asians.  Lee's sparring partner, Hawkins Cheung states, "Probably fewer than six people in the whole Wing Chun clan were personally taught, or even partly taught, by Yip Man".^[27] However, Lee showed a keen interest in Wing Chun, and continued to train privately with Yip Man and Wong Shun Leung in 1955

It does not say anything about Bruce having either a belt rank or a Sash rank.  So either he may have been unranked having not completed his training with Master Yip or Master Yip did not have a ranking system for his students. 

May be Bruce was revolutionary in his thinking and may be he did not like the belt or sash ranking system.  I find his style of martial arts Jeet Kune Do which he based on the philosophy of the Indian philosopher Jiddu Krishnamurthy to be very unique particularly at the advance stage which I am many years from achieving.  This style is speed, speed and more speed.   

Kung Fu schools do not award sashes. Wing Chun is a branch of Shaolin Kung Fu. It has three forms. Mastering these forms is the aim of the student to be proficient in the system.

I studied Wing Chung.  Five  Animal style of Shaolin Wu Shu and Tai Chi. These are all great martial arts style. I also studied Hwarando which is a one point form ( and the opposite of wing chung which is a chaining technique fighting style). If you want discipline, beauty of movement and of course great fighting skills, learn any of these traditional styles. They take years to master. If you want to fight well and kick  the behind of  90% of the people you will meet; learn MMA fighting style. It will only take six month of training to do that.

I was about to reproach you for inventing another personality(a student of Wing Chung) however you redeemed yourself by the last two sentences about MMA style. But you underestimate how long it takes to master the style, 6mths is not enough. People train for years to become good enough to fight in UFC or the other leagues. 

Dude , not because you live differently from me my life is an invention. I will be a wing chung student all my life. I performed the sim lum Tao today and had a good hour on my yook yan jong. 

No one said that you can be a UFC fighter in six months. I said that if you want to be able to beat up 90 percent of the world  in short order and for cheap, learn MMA. It is easy, quick and to the point. It has no rituals. Indeed karate fighters learn it faster.

An even worse statement, being able to beat 90 percent of the world in 6mths of training mma. Where did you pull this "fact" out of thin air? Six months training for the average person and if they have fear of fighting they couldn't beat a fly.

It takes much more than training, it takes guts too. 

90 percent of the people you will met never participated in anything past s shoving match. In six months anyone not clumsy and who can take instruction will indeed beat up the untrained. I would lay money on that.

If one spend 6 months on a mat getting abused I am sure they will have the requisite "guts". I have not pulled anything from thin air. Many of the amateur fighters in the local circuit would not have been training for more than that.

BTW even black belt kung fu and karate fighters never is able to fight off their feet. In self defense MMM one only has to focus on a few basic techniques and master them.

Is MMA a style or a sport for practitioners of various styles?

It means mixed martial arts, a mashup of the best of all of them with a foundation on Tai Boxing and the real mean parts of jiu-jitsu ( Brazilian)   wrestling and boxing.The kung fu is mainly in the kicks. It developed into a sport that is awesome but in self defense it is mean and nasty with even biting not excluded.

I trained MMA for a number of years and now do mostly kickboxing so I have some idea what MMA means. MMA is not a fighting style. Most major styles already incorporate MMA to one degree or another with the extremes being boxing (no holds, throws, locks) to wrestling/grappling - minimal striking. Everything else in between that I know of have some form of striking, throws, holds, locks.

It is not a fighting style as I noted. It is an aggressive mixed fighting  training strategy for a particular outcome. I was making the point that MMA style of training is the quickest route to be a good fighter.

I speak with some authority here since I have a second degree black belt in Kyokushinkai style and that took me almost 5 years. The rituals to that point includes three  taikyokus  ( beginners katas), fIve pinans ( advance katas, and three breathing  katas. These are time consuming and one has to pass one form to get to the next. 

Wing Chung also has three forms and one has to progress from one to the other no less than in Karate. I trained three years there and can only say I mastered one form and know the other two. The same with with Five animal form Shaolin Wu Shu. The forms are really hard to learn. These are all dedicated life styles strategies and while the fighting skills comes,  it  is incidental. The systems are about proper behavior and physical fitness and a spiritual approach to life. I presume Judo is the same

Military fighting  styles such as Krav Maga or US army style or even the earlier forms as the Korean Hwarando  are like present day MMA strategies dedicated to a quick learning process for maximum offensive force and focus only on one point strikes,  locks and holds with one intent, to incapacitate. This is the reason I said if one wants to learn to fight as a self defense class MMA style training is easiest and not the traditional route. Those are for people who want to dedicate a life to a spiritual experience.
