Guard, pronounced shǒu hù ?, is a Chinese word, which means guard and protection. From the biography of Sun Chuo in the Book of Jin: "I planted a pine tree before fasting, and I always guarded it." "Keeping" shows a kind of care and waiting, and it doesn't have to be around the guarded object. "Guarantee" embodies a kind of support and maintenance that gives up one's own safety and wealth. The guardian's contribution is often silent and unnoticed, which is a kind of forbearing emotion.

In a sense, "keeping" also means love. When you fall in love with someone, but you can't be with him, you will have the idea of silently praying for his blessing, hoping that he will be happy forever, and you will be really happy when you see his happiness. This behavior is guardianship.

Guardianship is not limited to love, its object can be important people or things or some abstract feelings and memories.

Guard's famous saying: 1. If you have a dream, you should protect it. -chris gardner; 2. A bosom friend is the patron saint of social order, which is inspired by individuals for self-protection. Maugham
