The bloody killing of the Three Kingdoms in Guan Gong began with the capture of the political emperor. Fair and selfless, dedicated to the country. Complain that there is no loyal minister, and sigh when you die! Red hare
First of all, there are two contents in your poem, one is Guan Yu, and the other is Red Rabbit. Your topic is Guan Gong, so you can bring a little red rabbit. So there are two themes in the content, and the topic becomes smaller.
Secondly, when you write an ancient poem, your teacher will definitely tell you some basic skills (that is, rhyming knowledge). Obviously, this poem didn't come true.
However, your poetic perspective is really good. I hope you will continue to carry forward.
