What I'm aware of in business is a four-pillar table. Even if one leg comes off, it will stand at the last minute.
Corona didn't affect us, but now there is a shortage of semiconductors, and the Setting PCs (work to set up and deploy computers) is stagnant. It seems to continue for a while. Fortunately, it is supplemented by other businesses, so it will not have a big impact for us.
If there were too many businesses, small businesses like ours would lose their strength.
However, if only one business, it will have a big impact if it collapses.
I remember again that it is only natural that we should not focus on just one business, but on the four pillars.
