The physiological activities of the human body are the ascending, descending, exiting and entering of the functional activities of qi. The science of life cultivation requires that these normal functional states should be maintained and restored in rehabilitation. Besides, attention should be paid to functional training, movement of physique to promote circulation of healthy qi, and harmonization of physiological functions of viscera and tissues. In this way, patients' abilities to adapt themselves to their individual life, family and social life as well as professional work can be to the greatest extent restored.

1. Visceral functions lie in coordination 
Convalescent patients still suffer from residual pathogenic factors and deficiency of healthy qi after recovery from wounds, handicap and diseases. Their visceral functions are not completely restored. Comprehensive measures should be taken to restore visceral functions as quickly as possible, and to coordinate other viscera according to the pathological features. For instance, as for a patient with liver disease during convalescence, not only dampness and heat in the liver meridian should be cleared away, but also the injury of the spleen and stomach should be taken into account.

2. Significance of viability lies in quality
Viability chiefly refers to daily living ability and professional working ability. Various ways should be adopted to train, conserve and restore functions in the fields of bodily movement, perception, lingual communication, life and profession, etc. to improve the life quality.
