鬧鈴時鐘

闹 = 市 + 门 : Napoleon (n) opened a shop (市) just inside the aorta's entrance (ao4) and it is bustling with noise (闹). His supermarket is so successful because he installed a trap door (门) in the floor above through which new customers keep falling.

铃 = 令 + 钅 : Li Qingzhao (li) is living next to engine, and her neighbors installed some very annoying little bells (铃) next to their entrance ((e)ng2). As a consequence she got an official decree by the emperor and a Ling Pai (令) that allows her to have them remove the bells, but as she visits the engine home no-one is there. Short-tempered she just uses her golden harpoon (钅) to take off the little annoying bells (铃).

时 = 寸 + 日 : Mnemonic symbol: a giant pocket watch.

The sun (日) asks Sherlock Holmes (sh) out for a coffee in the space station's kitchen (Ø2). Looking at his pocket watch (时), Sherlock sees he has time, winks and "thumbs up" (寸).

钟 = 中 + 钅 : Julian Giant Squid (zhu) practices trick shots in front of the engine ((e)ng1). He tries to hit a dart board (中) with golden harpoons (钅). He's not going for direct hits though, but trying to bounce the golden harpoons off of a huge bell (钟) first.
