What does Hongmao Xinda calligraphy mean?

The world is vast and there are many things to learn. According to relevant information, the source: Sima Qian's Letter of Appointment in the Western Han Dynasty: "People are inherently mortal, or they are heavier than Mount Tai or lighter than a feather, so they use it differently." Hong, this means a lot. Mao, which means lush. Caution is caution. Da means knowledgeable.
