Tips

history
Traced to ·杨泉《物理论》 (Yáng Quán's 'Wùlǐ Lùn', Jin dynasty): 上不正,下参差 'when the top is not straight, the bottom is uneven'. The longer beam-imagery version became proverbial in vernacular Chinese.
memory
Visualize a wooden house frame: if the top crossbeam (上梁 shàngliáng) tilts, the lower beam (下梁 xiàliáng) ends up warped ( wāi 'crooked, askew'). Used to scold parents/bosses/leaders whose subordinates have picked up their bad habits.
