Help to interpret a poem

I wonder what the landlord means by cracking. Do you mean to appreciate or just understand the meaning?

If you only understand its meaning, this poem has roughly the same meaning as the first floor.

The first sentence, "Madam sits in my humble abode", is about a gentle and dignified woman sitting in my humble abode.

The second sentence "Who can have two surnames?" It's about a woman who lives in such a simple house and waits to get married.

Three words: "Jade comes out of Lantian Dodd" Jade can also be regarded as the general name of women. lantian jade is the best of all jade, but even the beautiful jade produced in Lantian has its own beauty, not to mention that as a woman, everyone's moral character is different.

The last sentence, "Who can compare with Hongliang in Meng Guangli?" Meng Hong was a good wife and husband in ancient times. The so-called idiom is to take Qi Mei as an example, treat each other as guests and tell their own stories. The last sentence is illustrated by this allusion. Except Meng Guang, who can match Hong Liang?
