Because of the lazy loading mechanism of realm, it is not recommended to turn this enumeration into an array type at the data layer. The disadvantage is that the upper layer knows the storage logic of the data. Strictly speaking, we should not let the upper level know. But this design may be to facilitate the retrieval of the upper l
