Motto: Originally refers to the aphorisms written on the side of the seat to motivate, alert and restrain one's behavior. Later, one or a few aphorisms that are remembered by a person or often remind oneself are also called a motto.
Based on the above definition, the statement 'If nature knows, it will perceive the immutable law of prosperity and decline. It is the inevitable law of the development of human society to change, develop and advance constantly' is not suitable for use as a motto.
