鹤壁市

壁 = 土 + 辟 : Brunhilde (bi) was checking out the safety of the space station and found that the bathroom (Ø4) is a weak spot in the defence line if there should be any attacker. Thus, she decided to build a rampart (壁). She cannot do it alone though, so she asked the jade dragon (辟) for help. Together, they build the rampart out of earth (土). In this way, they will be able to fend off (辟) any intruder.

市 = 亠 + 巾 : Mnemonic symbol: a supermarket.

Sherlock Holmes (sh) started a supermarket (市) in the space station's bathroom (Ø4), but all he has for sale right now are berets (亠) and towels (巾). He should have opened it at the beach!
