Paying attention to people and life is the most important thought in Taoism and Taoist theory, and it is also one of its most valuable theoretical achievements. From Laozi's emphasis on "supporting one's life", "valuing one's life", "self-love" and "long life and long knowledge" to Zhuangzi's "supporting one's life", from Lu's Spring and Autumn Annals to Taiping Jing.
