To carry on the family line in poverty means that parents in the world have no regrets for their children, and they are worried that their efforts will not be understood or even misunderstood by their children, which makes people feel sympathy and regret. Parents' love is selfless and they don't expect anything in return. I am willing to work hard for my children, just asking them to dress well and live well.

In addition, it can also be understood that the kindness of parents in the world is admirable, in which "ability" means worth and should, and "pity" means cherishing and admiring.

This sentence comes from a poem by Cixi. On the seventieth birthday of Cixi's mother, Cixi didn't have time to attend her mother's birthday, so she asked the courtiers to send her many birthday gifts, and at the same time wrote a calligraphy by herself, framed it and sent it. This pair of calligraphy was preserved for several generations and was finally destroyed during the Cultural Revolution.
