Quatrains in modern poetry are not allowed in principle. But it also has a special physique, and the first sentence is flat and flat without rhyme. Even so, there are limits. Although it doesn't rhyme, you must use adjacent rhymes, that is, rhymes with similar rhymes. This grid becomes a "flying geese into the group grid". Examples are as follows: Sun Xun
Crossing the Temple of Qiao Feng
Dream back to the old days, and the green hills will not change their old appearance.
The moon sets at the temple near the bridge, and the pillow still smells midnight.
The rhyme of this poem is "Shang Er Dong", in which the first sentence "Zhong" is in the rhyme "Yi Shang Yi Dong".
The mo Xiang Xia sincerely offers.
