Why are there spears and shields?

Spears were invented first, because first of all, our ancestors wanted to poke others, not thinking that they would be poked. Since someone poked someone, someone must have been poked, so the wise man among the poked people invented the shield. He thought, with the shield, I can block it if you poke me, and then poke you with a spear if I block it. This is really a very good method. In this way, the person who poked people at first has been poked again. They learn from their mistakes, sum up their experiences and lessons, and finally equip themselves with shields.

It seems that LZ really loves it.

Laozi said: "Everyone knows that beauty is beauty and evil."

Size, like beauty, ugliness and black and white, is a kind of relationship or attribute arising from their opposition, which is relative and will be determined according to the criteria of judgment. We should not be bewitched by the words "big" and "small", but should understand the concepts contained in the words. Yes, big and small are such concepts. When you say one of them, whether you realize it or not, you are judging it with another concept.

Using TM dialectics means that you have me and I have you, which are both unified and opposite, and can be transformed into each other under certain conditions. If I have to ask why there are big and small, I have to keep silent and be defeated.

As for what is big and what is small, let's just say, is the whale big or not? Big, compared with the sky? Is the sand small? Small, but a world in a grain of sand.
