Sociality of practice: the struggle between man and nature is that man forms a certain social relationship and works together in social form. One can't fight against the powerful nature. Only by combining individuals into a unified whole in social relations and forming a social force beyond individual strength can we overcome nature. Historicity of practice: people's practical strength is formed and developed historically, and people in each era can only start their own activities on the basis of inheriting the practical achievements of their predecessors. Each generation has integrated the practical strength of the previous generation into their own activities and strengthened their practical ability.

Although practice can be expressed as individual activities of a single person, people always rely on the overall strength of human beings to have a relationship with nature and engage in practical activities.
