What is yin and yang? Does it mean that things will reverse when they reach the limit, or does it mean that things are black and white?

Even if it is dark, there is moonlight, even if there is photocopying during the day; There is sunshine in winter and shade in summer.

If black is black, then the person who is black is a psychopath? If white is white, then while doing good, it won't be broken?

There is Yang in Yin, and Yin in Yang means that Yin and Yang Can coexist. It depends on this.

The extremes will be reversed, as explained upstairs.

Almost, one has been ahead for a long time, and the energy consumption is almost the same, and the other strength will also rise. And another force exists in itself, always with us, and will not disappear.
