All the Goju Ryu Kata names are written in the Chinese language. Although today, this is often related in the 'Simplified' script - older Okinawan texts record these names as being written in the 'Traditional' script. This does not alter, change or otherwise disrupt the concept being conveyed - at least not when in the hands of a competent translator!
5) 四向战 (Okinawan Pronunciation 'Shoichin' - Chinese Pronunciation 'Sixiangzhan')
a) 四 (si4) = 4, four and IV
b) 向 (xiang4) = direction, face, advance and approach
The upper particle '宀' (mian4) represents a roof on a house (which possesses four enclosing sides). The lower (central) particle is '口' (kou3) which stands for an 'open' mouth. In the context of 向 (xiang4) it is said that an individual with authority is shouting so that everyone residing in the four-corners of the house can hear! Perhaps there is an element of 'protecting' or 'expanding' the conscious awareness (and 'will-power') into the 'four-corners'.
c) 战 [戰] (zhan4) = battle, war, conflict and attack (cause 'fear' in the enemy)
The left-hand particle is '單' (dan1) which denotes a net designed to catch and hold animals securely. The two boxes at the top symbolise weights - whilst the middle section is the net. At the base can be seen the rope that controls the entire mechanism. The right-hand particle is '戈' (ge1) - an ancient shafted weapon containing a stylised axe-head - similar to (but distinct from) the Western halberd or pole-axe, etc. The ideogram 战 [戰] (zhan4) suggests that through careful training, planning and deployment - a military engagement can be successfully implemented - in the four directions!
