Life science is a science that studies life phenomena and reveals the mysteries of life, thus benefiting mankind. Life science will develop in both macro and micro directions. On the macro level, from the study of organs and whole objects to the study of population, community and biosphere; Microscopic development, such as the development of "cell biology", "molecular biology" and "quantum biology", will inevitably integrate the macro and micro, and make in-depth research on different levels of life such as atoms, molecules, cells, individuals, groups and ecosystems as an organic system.
