Fu Zhen Song

Master Fu was famed for his Tornado Palm or what is now known as Rocket Palm.  This technique combined his trademark Iron Palm with a whirlwind-like spinning motion that he adapted from Ba Gua.  Any unfortunate assailant who dared cross Fu could expect to receive a blurred flurry of deadly Iron Palms.

Fu Zhensong learned Chen style Taijiquan before meeting Sun Lu Tang, under whom he studied Bagua. He was also a student of Ma Gui. Ma GUI, in turn, was Yin Fu's student. Therefore, Fu Zhensong took part in an important evolutionary stage in Bagua - in being exposed  to both Yin Fu (via Sun Lu Tang) and Cheng Tinghua's styles a convergence occurred.  This pattern of convergence and divergence apparently is repeated throughout Bagua history. 

Most of Master Fu's forms have the Yin Fu linear patterns, while the more advanced ones are the more flowing and circular Dragon Style of Cheng Tinghua.  To top it all off, Fu Zhensong added his tornado palm techniques to all palm and weapons forms.  Of all the Bagua styles today, only descendants of Fu Zhensong's style use his trademark Tornado Palm heel spinning technique.

Fu Zhensong' s style was just recently recognized by the Chinese wushu association as the sixth official legitimate style of Bagua.
