It's a bit difficult to explain what this temple is. The cult that this temple stands for, is a combination (hybrid) of Taoism (including it's popular religious form), Buddism (from India), and Confucianism (an institutionalised body of knowledge in ancient China with special emphasis on "this-world"). The photos are named after the Chinese calligraphy that appeared in the photo, and I hope my translation is accurate.
#1 The Precious Cave of Purity and Spirit;
#2 The Flowery World is an Emptiness;
#3 Observe Yourself;
#4 The Door of Confucianism.
