都是小老师装什么大校长
[dōu shì xiăo lăo shī zhuāng shén me dà xiào zhăng]
Translated as 'all are small teachers, pretending to be big headmasters,' this name sarcastically points out the inconsistency between one's actual position and pretension. It criticizes people who behave as if they hold higher authority or importance than they really do.
