禁止令行

禁 = 林 + 示 : There's a small forest of two Christmas trees (林) in front of the encampment ((e)n4). Although there's a sign clearly stating that it is forbidden (示) to touch the trees, Joan of Arc (ji) set up her guideon (示) so that it is supported by the two trees and she can practice pull ups.

止 = ⺊ + 丨 + 一 : Mnemonic symbol: a barrier. James II of England (zh) is marking his area in the space station's living room (Ø3) with a big barrier (止), in front of which he sets up his pennant (⺊). He places a soldier left and right to the barrier, armed with a dinosaur bone (丨) and a flute (一) respectively.

令 = 今 + ㇏ : As a mnemonic symbol, I'm going to use a 令牌, which was a tablet to identify someone as an official sent by the emperor to convey the emperor's orders.

令 = 今 + ㇏ : Li Qingzhao has been sent by the emperor to collect rent from the English, but they are nowhere to be found. Finally, Li Qingzhao arrived at the engine's bathroom, ready to show her 令牌, raise the finger and show to the date of payday on the calendar—if there were anyone in the engine's bathroom.

行 = 亍 + 彳 : Mnemonic symbol from "to travel": seven-league boots.

Xi Shi (xi) is tired of walking with a black sneaker on her left foot (彳) and a full armor boot on her right foot (亍). Fortunately she finds seven-league boots (行) in the engine's kitchen ((e)ng2).
