Of course not. This is a common expression that parents encourage or urge their children. It may be true from a certain evaluation system (high school only score theory), but it is obviously not true to open your eyes.

Take Fudan, my campus, for example. People who are unwilling to be mediocre can spend four years here. However, on the other hand, it is still decadent. These students who are lost in confusion and predicament are enough to deny the landlord's assertion.
