However, it is a difficult problem to ask what the surname and name of this "Erlang God" is. That is to say, taking the Erlang Temple in Guankou as an example, the contradictions caused by various opinions are reflected here: according to the record of searching for gods in the Origin of Three Religions, this temple should be a Taoist temple, and Erlang gods are Zhao Yu and Zhao Erlang, who were posthumously named as "the true king of Qingyuan Miao Dao" in Song Zhenzong; However, the statue of Erlang God in this temple was a young husband, wearing a helmet and armor, and did not need powder. The most striking thing is that he has an eye on his forehead, a three-pointed double-edged knife in his hand, and a roaring dog in front of his soap boots, which makes people know at a glance that this is The Journey to the West and Yang Erlang or Yang Jian depicted in The Romance of Gods. Surprisingly, scholars of all ages praised Erlang God as the son of Li Bing, the guardian of Shu County in pre-Qin Dynasty, for the plaques, couplets and stone carvings embedded in the temple walls.
