During his practice, Zhou Tong let out a mountain-crumbling scream and fell onto his back while kicking one leg into the air. Wu Song felt sorry for Zhou Tong because he thought maybe the man was too old to practise the martial arts and had lost his balance. However, Zhou Tong screamed once more and this time he shot high into the sky with his swords pointed upward towards the moon. After watching him land and perform a few punches and kicks, it finally dawned on Wu Song that Zhou Tong was indeed practising the boxing routines of the immortals Iron-Crutch Li and Han Xiang from the Drunken Eight Immortals style. Zhou Tong was so good at this style that his performance once caused a fellow warrior to become intoxicated. Puzzled, Wu Song remembered back to his own martial arts master who had told him there were only two people in the world (including Wu Song and his master) who could perform such boxing. Zhou Tong also knew the style too. Because Zhou Tong's performance was so great, Wu Song went against the rules of etiquette and shouted praise from the top of the wall.
