What does an old orphan mean?

At that time, villagers called families without sons "orphans", meaning that only daughters without sons meant no descendants, and family contacts were cut off from then on. As a result, the old grandson with only six daughters justifiably became the "orphan" of the whole village population.

No valley means no valley, also called "no _". The valley of Shuo Wen He Bu, continued, is the general name of 100 valley. The original intention of "no valley" is fruitless. If rice is not grouted, there will be no rice. This is called "no food". For people, there is no child, an old orphan.
