In early 1939, after the Japanese invaders occupied Guangdong, the East River Column, which continued to fight, formed a city action team. This unit did not fight in high mountains or vast fields, but in the bizarre urban landscape. Each member of the action team possessed unique skills. There was the captain Qi Zhonglei, who came from a Japanese military academy and excelled in various firearms, nicknamed 'Lieutenant'; Mei Yanfang, who came from a wealthy family and was skilled in lightness martial arts, hand grenades, and deadly throwing knives, nicknamed 'One Cut Mei'; the loyal and clumsy yet skilled northern hunk Ma Zhenkui, nicknamed 'Crutch Horse'; his sister Ma Lanlan, who was adept at demolition and specialized in putting down various opponents, nicknamed 'Blue Phoenix'; the charming and skilled information scout Lei Xiuzhi, nicknamed 'Nine-Year-Old Red'; and the silver-tongued and master of disguises Liu Xianglin, nicknamed 'Young Master Liu'. This small group acted like ancient swordsmen, always infiltrating the heart of the enemy to deliver a heavy blow to the Japanese invaders.
