I say 'Form' - but the ideogram used is '套' (Tao) which usually refers to a 'Set' or a 'Pattern' of prescribed movements (that is a 'routine') - as opposed to '形' (Xing) meaning 'Form' or 'Shape' (pronounced 'Kata' in the Japanese language). Whereas '套' (Tao) refers to a set movements (like beads strung on a cord) - the term '形' (Xing) refers to the heart or foundation of a Style which 'manifests' through every movement that is performed.
As within Goju Ryu - the 'San Zhan' (Sanchin) Form is learned first - and then seems to be followed by the first and second 'Sets' included above (although 'San Zhan' is also referred to as a 'Set'). The translation is a little laboured as a 'Fortress' is mentioned which has its immediate environment (around the foot of the external walls) continuously 'cleared' of enemy attackers! The Xiangdian Fist practitioner 'prepares' to achieve this function through correctly practicing these 'Sets' - the sum total ability accrued is then used against an attacker(s). Or, a robust defence 'removes' the threat of any attacker - as the Xiangdian Fist practitioner is always 'prepared'. I am wondering whether any of this might relate to the development (in theory at least) to the 'Gekisai' (撃砕) [Attack-Shatter] Kata developed by Miyagi Chojun? Below are two videos showing how effective Xiangdian Fist can be:
The second video features a Seventy-year-old old Master who wants to carry forward local martial arts in Fuzhou - and teaches young people Xiangdian Fist for free:
