In the last ten years or so even respected grandmasters of traditional styles have begun to accommodate this contemporary trend towards shortened forms that take less time to learn and perform. Beginners in large cities don't always have the time, space or the concentration needed to immediately start learning old frame (75 movements). This proves all the more true at workshops given by visiting grandmasters. Consequently, shortened versions of the traditional forms have been developed even by the "Four Buddha’s warriors." Beginners can choose from postures of 38 (synthesized from both lao and xin jia by Chen Xiaowang), 19 (1995 Chen Xiaowang), 18 (Chen Zhenglei) and 13 (1997 Zhu Tiancai). There is even a 4-step routine (repeated 4 times in a circular progression, returning to start) useful for confined spaces (Zhu Tiancai).
