What does it mean to be poor and not die?

It means that even if the son-in-law is poor, he should not rent land in his father-in-law's house.

From:

If you die of poverty, you won't plow, and if you starve, you won't enter the radish garden.

The poor died without plowing the land. There are two interpretations of this sentence. The first understanding is that in ancient times, some poor son-in-law had no land at home, while the old father-in-law had land at home. The poor son-in-law had to rent land in the old father's house to make a living.

But in ancient times, married daughters were like spilled water. The daughter didn't get the property of her parents' family and had no obligation to support the elderly. They just took time to visit their parents. In the face of interests, the old father-in-law must be towards his son. In this case, the poor son-in-law also rented the land of the old father-in-law's family, which may not get the corresponding return, and may also cause the contradiction between his uncle and Lang.
