When reading a cross poem, you can divide each line into two groups with five words in each group. One group usually expresses the theme or emotion, and the other group provides details or descriptions. The two groups are separated by commas or spaces.
Here is a simple example:
I, love, you, so.
Deep, deep, beautiful, affectionate and sentimental.
Like, heaven, space, yes.
Ming, Moon, Reflection, Photograph, Magnitude and Earth
In the above example, the first line expresses the theme, that is, the author's love for someone. The second line provides affectionate details, that is, the author has strong and profound feelings for that person. The third line uses the bright moon in the sky to compare the author's feelings, and the fourth line uses the earth to compare the loved ones.
In short, when reading a cross poem, you should divide each line into two groups to understand the relationship and significance between the two groups.
