南下

南 = 十 + 冂 + 丷 + 干 : Mnemonic symbol: a palm tree (palms are only found in the south)

南 = 十 + 冂 + 丷 + 干 : Napoleon and the mean crocodile met in the anthill's kitchen to discuss a secret plan. The mean crocodile found a map which leads to a treasure of dried fruits. Napoleon and the mean crocodile agree to follow the map and claim the dried fruits, but each of them has his own secret agenda: Napoleon wants to claim the land and put up his big cross, and the crocodile just wants to relax under a palm tree.

下 = 一 + 卜 : Mnemonic symbol: from the up/down logic, and a little bit the shape of the character, a ladder.

Xi Shi (xi) is on a retreat in the ashram. Using a voodoo staff (卜), she divined that next (下) week she'll have to play the flute (一) sixteen hours per day. Because she hates playing the flute, she climbs over the ashram's bathroom (a4) wall using a ladder (下) to escape.
