The following are the metrical requirements of the Seven Wonders. It is a good attempt for you to create original poems.
But I hope to study the basic requirements of writing poetry, otherwise there will be no progress if I write too much.
Seven-syllable/seven-syllable quatrain
Type one
Ping, ping, ping. (rhyming) even and plain. (Rhyme) Example poem: The southern tour made Gong Dou sad, and he wanted to ask about the past, but he never turned back when he saw the river. At dusk, the east wind and spring grass are green, and the partridge flies to Yuewangtai.
Type 2
⊙ Ping ⊙ Ping, (rhyme) ⊙ Ping, Ping. (rhyming) even and plain. (Rhyme) Example poem: I left Wang Changling for Qin, and the people of the Long March did not return. If Wei Qing, who attacked Longcheng, and Li Guang, the flying general, were alive today, the Huns would not be allowed to go south to spend their horses in Yinshan.
Type 3
⊙仄仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 仄 (Rhyme) ⊙ Flat ⊙ Flat ⊙ Flat. Example poem: I miss my Shandong brother Wang Wei on vacation in the mountains. I am a stranger in a foreign land, and I miss my relatives every holiday. When I think of my brothers' bodies climbing high, I will feel a little regret for not being able to reach me.
Type 4
⊙仄仄仄仄, (rhyming) ⊙仄仄仄. (Rhyme) ⊙ Flat ⊙ Flat ⊙ Flat. Example poem: I joined the army in Wang Changling, a dark snow-capped mountain in Qinghai, and looked at Yumenguan from the lonely city. Yellow sand wears golden armor in hundreds of battles, and the broken loulan will not be returned!
