The first and last words of the topic should start with capital letters, and the middle words (including those after hyphens in collocation words) should also be capitalized, except articles, coordinate conjunctions and, or, but, nor, for and prepositions, except infinitive to.
For example:
I visited the Forbidden City for the first time.
People without a country
In addition, the words at the beginning of the next sentence do not need to be capitalized at the beginning of each line, but after the end of the poem, just like sentences.
For example:
You are my best friend.
Besides wanting to give us the best,
You showed me again and again.
You want to give me the best.
You want me to be happy.
You always think of me.
