The name of "Two Paradise" comes from two sentences in the Ming Dynasty's enlightenment book "Study in Qionglin": "Feel the grace of saving the world, and say it again; Recite the virtue of two days of regeneration. " It is with this kind of compassion to heal the wounded and rescue the dying and use drugs to save the world that the predecessors in heaven are committed to casting a second life for patients and recreating a second life.

In the late Qing Dynasty, Ertiantang opened its first store at No.483 Yide West Road, Guangzhou.
