At a bit more sophisticated level it is called sikulian, or "four line responses." Two people trade statements four lines in length, each answering the other's previous reply. The goals are verbal parallelism and rhyme; it offers a strong poetic appeal.
講究一點以「四句聯」形式表演，兩個人「你四句來我四句去」，我講完來換你講，講求對仗及押韻，非常有念詩的味道。
