to finish / to achieve / variant of 瞭|了[liao3] / to understand clearly
Mnemonic symbol from "to finish" and the shape of the character: a prize cup.
Li Qingzhao (li) is responsible for manufacturing a prize cup (了). She only needs to add a poetic engraving. Unfortunately, she suffers from a writer's block. In the aorta's living room (ao3), someone left a cryptic message engraved on the walls using a sickle (乛), which is still lying on the floor. Being an accomplished poet Li Qingzhao is able to understand the message clearly (了), realizes its poetic potential and starts to engrave it on the prize cup using a crowbar (亅).
