Pun design:
Spider + descending from the sky
Punning mechanism:
‘Zhi zhu (蜘蛛, spider)’ has a nickname ‘xi zi (蟢子)’ or ‘xi zhu (喜蛛)’ meaning the ‘lucky one’ or ‘lucky spider’.
Its first character ‘xi 喜(蟢)’ for ‘happiness (good luck)’ is then combined with the phrase ‘cong tian jiang (从天降)’, meaning ‘descending from the sky’.
The whole phrase (喜从天降) describing the spider’s action in the picture is to convey the meaning ‘pleasant surprise descending on you’.
画面要素：蜘蛛 + 从天降
谐音机制 : 取蜘蛛的别名‘喜蛛’谐音‘喜’; 某物自天而降，取‘从天降’
