According to Maslow’s Hierarchy of Needs(Maslow’s hierarchy of needs is a theory in psychology proposed by Abraham Maslow in his 1943 paper “A Theory of Human Motivation” in Psychological Review.), Needs has often been represented in a hierarchical pyramid with five levels.  The four levels (lower-order needs) are considered physiological needs, while the top level of the pyramid is considered growth needs.  The lower level needs must be satisfied before higher-order needs can influence behavior. The levels are as follows:

• Self-actualization – includes morality, creativity, problem-solving, etc.
• Esteem – includes confidence, self-esteem, achievement, respect, etc.
• Belongingness – includes love, friendship, intimacy, family, etc.
• Safety – includes security of the environment, employment, resources, health, property, etc.
• Physiological – includes air, food, water, sex, sleep, other factors towards homeostasis, etc.         What kind of needs for Chinese jade collection? Should it be the need of Belongingness? or Self-actualization to save the cultural heritage of the world.
