Roman arrived at the hospital to check on the situation.
These people need supervision.
Those people have lived in such an environment for so long.
They never realized what was bad; no one ever told them to wash hands before meals.
Now Roman has come and told them they need to wash their hands.
Some people easily change and are firmly convinced.
Because it's the lord's order, the lord has high prestige, and whatever he says is right.
But some people are hard to change, stubborn as ever.
You may be right, but washing hands before meals is too troublesome.
Just by adding this inconspicuous step, Roman's will faces hidden resistance, there's always someone who will slack.
Therefore, it needs supervision, and he has to supervise it himself.
Roman can't manage every household, but he can manage public hospitals, hygiene standards must be enforced.
The old customs and bad habits of the past must not make a comeback.
