会发光的都是电灯泡
[huì fā guāng de dōu shì diàn dēng pào]
'Anything that glows is a light bulb'. The phrase reflects humor or cynicism towards people getting attention, comparing them to light bulbs which shine only because they consume electricity; it may imply these persons are not genuinely shining from within but using external sources. However, it can also imply positive aspects about shining or radiating positively, just like a lamp.
