Mnemonic
[c-] Casper is in [1] front of the [-ao] barn, at night, doing some 操 exercise. Yes, even ghosts need to stay in shape. He grabs the trunk of a 木 tree and puts a bunch of 品 goods on each end, then lifts it up and down with his 扌 finger. Casper, like all ghosts, have superhuman strength. Some roosters outside watch him 操 exercise, slightly terrified.
