What is the correct punctuation of this couplet?

A couplet was posted, which said, "This year will be good, with less bad luck, and no lawsuits." But there was no punctuation. As a result, the younger son read this couplet when he came to visit relatives, which surprised the whole family. What he read was: "This year is very unlucky, and there will be few lawsuits." He said that in ancient times, there was a poor scholar who went to a friend's house to make a living. As time went by, the owner became unhappy. One day, it was raining, and the poor scholar came again. The master had no choice but to write a note to express his feelings tactfully. The poor scholar read the note and knew that the host was issuing an order to exclude guests, so he had an idea and just used a pen to add punctuation on the note, and the order to exclude guests became a word of stay. Do you know how host and guest break up sentences respectively? When it rains, I invite you to stay. If God wants to stay, I will stay. If it rains, I will stay.
