A masterpiece of martial arts from the "Northern School" of the Republic of China. Yang Luchan was frail since childhood and often fell ill, but he was eager to learn boxing from the master of "Chen Style Tai Chi". In order to get close to Mr. Chen, he was willing to pretend to be mute and clean her door every day. He even fainted from the cold. As expected, Mr. Chen was so impressed that he was taken in as a domestic servant and had the opportunity to "steal boxing" and learn skills. On a chance occasion, he couldn't help but applaud Chen's skills, and his "mute" identity was exposed! His infatuation finally moved the other party, and Chen made an exception and took him under his tutelage and taught him all his kung fu. Later, he developed the Yang style Tai Chi based on the Chen style Tai Chi, and defeated all the invincible opponents in Beijing, becoming the great master "Yang Invincible".
