不分高下

不 = 丆 + 卜 : Bruno Bear (bu) is setting up a wind wheel (丆) with a voodoo staff (卜) in the space station's bathroom (Ø4). He also puts a "forbidden" sign (mnemonic symbol for 不) on it, to make clear that it may not (不) be stopped.

分 = 八 + 刀 : Symbol for this character: A stopwatch (from the meaning "minute"). Frankenstein's monster (f) participates in the annual championship of chopping eight-balls (八) in front of the encampment ((e)n1). Using a cleaver (刀), he chops (kind of divides / separates (分)) as many eight-balls as he can in one minute (分).

高 = 亠 + 冋 + 口 : A skyscraper.

高 = 亠 + 冋 + 口 : Just in front of the aorta, a huge skyscraper has been erected. It's an important building, so there's a control checkpoint at the entrance, and Guy Fawkes has been hired to stand guard. To make him look more dangerous, he wears a beret. However there's no-one to check, so Guy Fawkes is bored and eats a mandarin.

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.
