The thinkers nearly didn't permit to neglect the topic during the climax of Three-in-one Doctrine in middle-and-late-periods of Ming Dynasty. But the thinkers follow their religious ideas in merging way. Both Wang Long-xi (王龍溪) and Lin Chao-en (林兆恩) were affected by the thought of Wang Yang-ming. Their views of Three-Doctrine were based on Confucian thought to merge with Buddhism and Taoism. However, no matter it wan the Three-Doctrine to be included in conscience in Wang Long-xi's theory, or the Three-in-one Doctrine of Lin Chao-en's theory, both referred to the foundation of mergence. So I will research the conscious views between Wang Long-xi and Lin Chao-en. Also I will compare the views of ”ti yong (體用)” and ”xu ji” (虛寂) to distinguish their same and different opinions. By way of the comparison, I will display the multiples based on Confucian thought to merge with Buddhism and Taoism.
