世务

世 = 廿 + L : Mnemonic symbol: the WTO or WHO.

Sherlock Holmes (sh) is cleaning a flower pot (廿) under the shower of the space station's bathroom (Ø4) with a loofah (L) because he didn't quite understand a poster next to the shower from the WHO (世) explaining dangers arising from different germs.

In this case, L is for loofah.

务 = 力 + 夂 : Willy Walrus practices a performance in the space station's bathroom. To honor the CCP, he dances wearing high heels. The grande finale is a banner that is unrolled upon hitting a power button, which reads "为人民服务".
