If you find that the old man is ill and the situation is not good, you can consider buying a cemetery.
Assuming that the elderly are not too ashamed of this matter, they can ask for the consent of the elderly before buying.
When it is inconvenient for the elderly to know this, it can be decided by their children.
According to the traditional concept of China, buying a cemetery during illness has a festive concept, which sometimes has unexpected effects.
Since we are considering buying a cemetery, we will buy it sooner or later, so it is better to make a decision early.
