Great love generally means that you would rather lose your own interests and achieve others; Or loyalty to the country.
Small love can generally refer to the feelings between men and women, or the sense of responsibility and belonging to the family.
In fact, there is no difference between the two in essence. It is a noble spirit, a deep affection for people and things around you, and a heartfelt preference and research. But from the object, there is a difference. Little love generally refers to people who are closely related to themselves; Great love is more of a sense of social responsibility and patriotism.
From small to large, from near to far, love, affection, mutual assistance, and contribution to the country all illustrate a person's feelings and ethics.
