postures, and jumps including a jump kick. However, some lineages have since modified certain aspects of this form to align with their curriculums. In 1914 when Hao Weizhen first taught in Beijing, this form was performed in about eight or nine minutes, the same speed at which Yang Chengfu and Wu Jianquan were timed doing their own long forms that decade in largely the same sequences we know today. All these forms were performed at a varying slow-swift tempo then, usually with jumps and fa jin. The 1977 film of Li Baoyu disciple Ouyang Fang's performance of this form is like a time capsule for us, with few if any changes from the original he'd begun learning almost fifty years before. In the early twentieth century, t'ai chi forms were still intended for martial artists who also spent long hours each day training on individual moves and their applications, often after years of experience in other martial arts. Yang Chengfu and Wu Jianquan modified their primary training forms to a slow even speed, removing jumps and fa jin, to make the art more accessible for the health of the broader public with the encouragement of government officials. But Hao Weizhen's form retained speed, jumps, and fa jin for decades, because the next generations developed other forms to meet the new goals. The Li Baoyu lineage has preserved this form relatively unchanged, as documented in the 1998 book 郝式太极拳 (Hao Style Taijiquan) written in collaboration with Li Baoyu's daughter Li Guihua. It is practiced with some minor variations among schools in Hebei and Shanxi, where it is taught at the original nine-minute pace and at a slower training pace of about fourteen minutes, but only in the worldwide Dong family t'ai chi sub-branch is the focus primarily on a slowed down and smoothed out pattern. That version retains the evident internal strength and structure that has led the Dong lineage to call this their "Hard Form" (in contrast to their primary Yang form), and it still includes some fa jin moves. They perform it in about eighteen minutes, giving advanced students time to focus on the unique Wu (Hao)-style internal training it offers, because this is the only Wu (Hao) form in the Dong curriculum. But in those schools it is supplemented with Dong family fast forms, which include sections that incorporate techniques and principles Dong Yingjie learned from Li Baoyu,
