1. When relatives are kind to you in childhood, it's because your parents are capable. When relatives treat your parents poorly in adulthood, it's because you lack strength. Besides parents, any relationship is a performance. As long as interests align, others won't act tired. The only ones who will never betray you are your parents. Money in your pocket and all relationships are interests. Where there are benefits, people's hearts will follow. Those who kick you when you're down are your own people; those who laugh at you are not outsiders; and those who don't wish you well are close to you. Don't overestimate your relationship with anyone.

2. To ruin a family, often only one sick person is needed; to support a family, sometimes only someone who values life is enough. Whether life is simple or prosperous, having someone in the family who understands health and insists on exercise is the family's blessing. When you're in a low point, health is your last trump card; when you're successful and proud, health is your ace to hold everything.

3. Don't get too close to relatives; proximity can breed resentment. Don't get too close to acquaintances; closeness can hide trouble. There is a rule between people: "The closer you are, the more humble." When too close, respect diminishes, understanding lessens, and the original good may turn sour. Healthy relationships are never "you and me are different," but are about appropriate closeness and distance. Don't drink more than six parts intoxicated, don't eat more than seventy percent full, and don't treat others with more than eighty percent sincerity. Like two trees, only when separated by the right distance can they root themselves and grow toward the sun together.

4. The difference between experts and ordinary people is: the ability to endure pain, to keep silent when necessary, and to hide things in the heart. Beginners who want to become experts must first temper their mind: stay humble in prosperity, remain calm in adversity, stay grounded when high, and not become discouraged when low.
