Introduction to the Enlightenment Spring: There is a spring where the water of Caoxi flows through the valley of Yutang Village. Because the Sixth Patriarch passed through this place when he was enlightened and gained spirituality, it was named "Enlightenment Spring", also known as "Wisdom Spring". The spring water has a constant temperature all year round and comes from the same source as the Kowloon Spring where the Sixth Patriarch of Nanhua Temple washed his cassocks. The water quality of Enlightenment Spring has a high content of metasilicic acid, especially calcium, so it has the characteristics of particularly clear and smooth water quality, which is good for regulating the human body's mind. Vascular system, nervous system and endocrine function are all greatly benefited.
