Pinyin
cháng fēng
Simplified
肠风
Literal
腸風 cháng fēng — wind that has long been in the interior and has settled in the intestines, where it gives 飧泄: stool that passes the food undigested.
Shuowen
《說文解字》：腸，大小腸也。从肉昜聲。「腸」讀 cháng，**本篇1見，即此**；**「久風入中」——「中」讀 zhōng**；**「飧」讀 sūn**——**王冰「飧泄者，食不化而出也」**；**「泄」讀 xiè**。

In brief

Intestinal wind is wind that has lingered long enough to reach the interior. Wang Bing gives the mechanism: with wind in the intestines the food is not transformed and passes out as it went in. It is the only entry in the chapter’s catalogue of ‘how it was caught’ that is named for duration rather than for an act.
