What kind of poem does Huang Tingjian's play title belong to?

Huang Tingjian in the Northern Song Dynasty

Take a walk, have a rest and comfort the tired.

Sunny, bright, playful and harmonious.

The grass is deserted and the room is dusty.

The servants waited on the side, and the river was clear and muddy.

There is a strange form in couplets and poems, that is, every sentence is written in Chinese characters with the same radical or radical. The word "Lian bian" comes from Liu Si's "Wen Xin Diao Long Lian Zi": "Half-character is homographs with different meanings", which is a unique rhetorical way of Chinese characters. The couplets written in this form are called "Lian Bian Lian". Poems written in this form are called "frontier poems". Even-sided poems should take into account the fluency of content and sentences, so it is very difficult to write such poems, which are also called "same-sided poems". Poems with every sentence on the same side are called same-sided poems. Once upon a time, there was a boatman who posted such a couplet on the boat: the rivers and lakes are bright, the waves are clear and the waves are clear; Freedom and travel are alliances.
