Meeting guests at the Eight Immortals table means meeting guests at the Eight Immortals table. The Eight Immortals refer to eight Taoist immortals, including Han Zhongli, Lan Caihe, Zhang, He Xiangu, Lu, Han Xiangzi and Cao Guojiu, representing eight different personalities and abilities in the world. But the general saying is "square table". In understanding, a square table is a square table and a typical representative of a square table.
As for the animals you mentioned, this may involve some misunderstandings. The Eight Immortals are not animals, but immortals. Therefore, no animal can be directly equated with the Eight Immortals.
