Is traditional martial arts worthless?

Of course not. Traditional Wushu is a legacy of China's ancestors. How can you say it's worthless? Traditional Wushu is very beneficial for people to keep fit, exercise and keep healthy. Although the main purpose of China Wushu is not to attack and fight, it is not as strong as the martial arts novels say, but it doesn't mean that it can't attack and fight at all. Martial arts can still be used to attack and fight to a certain extent, and can be used for self-defense. So it is wrong to say that traditional Wushu is not worthless.
