The train of life must move forward without end. The most important driving force is not wealth or love, but morality. If there is no morality, all the wealth and emotions that people get will only hinder the progress of the life train. In love, there is no right or wrong, but there is courtesy and integrity. For some emotions, you must know how to let them go without hurting them; for some choices, you must follow morality. In the face of temptation, there should be unambiguous moral boundaries, keep the inner prudence, and treat these-worldly fireworks with a clean heart.
