The first part: What is the second part of father Jinshi and son Jinshi?

An old joke. Once upon a time, there was a rich man who posted couplets on his front door to promote himself before the Spring Festival. The first couplet: father Jinshi, son Jinshi, father and son Jinshi, old lady, young lady, old lady. Many passers-by shook their heads after reading it, which is too exaggerated. A scholar passed by and added a few strokes with a brush and ink, which caused passers-by to burst into laughter. The old rich man fainted at the sight, and his son and daughter-in-law stamped their feet and swore! After the change, the first part is that the father goes to the child, and the second part is that the old man loses his husband and the young man loses his husband.
