Tianmen, Yue Long, is the tiger lying on the phoenix que dual?

Tianmen Yuelong and Fengque Crouching Tiger should be dual, because the antithetical sentences are characterized by neat antithesis, distinct rhythm, neat and beautiful appearance, easy to remember, and the word structure and part of speech are the same. These two words are four words, and there are dragons and phoenixes, and the verbs in them are also corresponding. So these two words should be said to be double.
