谁

隹
:
Just inside the Eiffel Tower's kitchen Sherlock Holmes stands proudly in front of an advertising column advertising his performance in the Eiffel Tower tonight. He is very upset as two sparrows fly by and ask each other, "这是谁？是谁？"
知
=
口
+
矢
:
Mnemonic symbol: Francis Bacon is attributed to have stated "scientia potentia est", "knowledge is power". I'll thus represent 知 by Francis Bacon. Francis Bacon (知) and James II of England (zh) are playing darts (矢) in front of the space station (Ø1). Because they lack a dart board they just use a mandarin (口).
