Many people born after the 1980s are the only child of their families and they might not understand references such as “brotherly love" or “the eldest brother takes on duties of the father”. However, giant pandas are different. What they can feel is “accompanying and taking care of each other and the deep love between brothers”.
Chasing and romping on lawns, leaning close to you and flirting with you, and jumping up and down and play acting with you--these are experiences of growing up together. When you are young, you are playmates; when you grow up, you worry about each other; and when you get old, you rely on each other. This emotion is power, warmth and courage. You must cherish each other forever.
