What is the essence of a strong person? How do you define a strong person? Is it a person with a strong body, a person with a smart mind who can bring huge benefits, a person who can convince everyone, or other types of people?
A person with a strong body refers to an individual, and may also be a person with great influence, who has a strong body through his personal exercise or training.
A person with a smart mind who can bring huge benefits to himself or others must be an individual, and then through this model, he can benefit others, which is also a manifestation of a strong person.
