He also share the credit as one of the originator of Bagua Taijiquan - a style that is being practise in Jinan (capital of Shandong Province). 
There are many stories describing the skills of Liu DeKuan. In one story, Cheng Tinghua's eldest son,Cheng Haiting, was teaching the art in a field outside the Suiwen Gate on Ximo Street. Famous practitioners from both Yin Style and Cheng Style Bagua often came in their free time to sit and linger. Big Spear Liu, in his old age, suffered form an eye disease. Both of his eyes were not bright. However numerous students still wanted to compare skills with him. They only needed to bring the shaft of their weapon in contact with Liu's spear shaft to try to lift it up. Liu would stick to their spear shaft and advance. The opponent would lose his weapon and be thrown by his strike."
