Qin Dynasty.

Ying Zheng looked at the black crow in the light curtain, and thought of the fact that the Qin Dynasty respected black.

Not only did he not dislike this not-so-good-looking bird, but he liked it very much.

He even had the urge to make the crow the national bird.

As for pigeons, in Ying Zheng's eyes, they were not the so-called symbol of peace at all.

It is just a tool for delivering letters, and it can be used to satisfy your cravings occasionally.

But after watching this video.

Pigeons have no edible value. They carry germs all over their bodies and spreadDisease.

I dare not eat it at all.

The pigeons only have the function of delivering letters, and there is no other value at all.

Ming Dynasty.

Zhu Di glanced and saw a crow on the wall of the Forbidden City.

He snorted coldly: "Crow?"

"This is the name given to them by later generations, so ugly."

"It should be called the Three-legged Golden Crow."

If the crow is really a symbol of disaster, why would he raise such a bird in the Forbidden City?

Crows can warn of disasters in advance, which is clearly a good omen!

As for their unpleasant calls, they are just reminding people.

Zhu Di felt wronged for the crows.
