Why is morning glory called morning glory?

So why do people give it such a name? It turns out that its name has a story. A long time ago, there was an unnamed place, and I don't know when a mountain appeared that looked like a cow, so people called it "Funiu Mountain". At the foot of this mountain, there is a small village with not many people. One of them has a bunch of twin sisters. Because the villagers are poor and have no money to buy cattle to plough the fields, they can only make some clumsy tools to plough the land.

The twin sisters, on the other hand, have reclaimed the wasteland before and after the mountain and planted it with their own hands. The two sisters are kind-hearted and willing to help people who are poorer than they are. One day, the two sisters were digging the ground, and suddenly they could not dig. It turned out that there was a very hard thing. The two sisters could not dig it up anyway, so they sat aside and had a rest. Suddenly, the hard thing opened, and my sister saw a shiny thing. They took it out and looked at it carefully. It was a silver horn.

They were surprised when an old man came up to them with a smile and said, "this mountain was brought down by the Jade Emperor in order to suppress a hundred monsters." Because these spirits and monsters have been transformed into human form, but they do evil in the world regardless of it, so the Jade Emperor paid them and put them here. It has been 900 years today, ah, and tomorrow they will become golden and will no longer harm the world. This trumpet is the key to the mountain. Tonight we will hear the sound from the mountain, and then there will be a golden light. There are the eyes of the mountain. Just plug this thing in, but you have to remember the formula. Then the eyes of that mountain will get bigger, and you can go in and hold a Taurus so that you don't have to worry about food and drink for the rest of your life. This key appears only once in 900 years, and it is useless at dawn. Don't be locked up in it, or you will definitely die. Besides, you can't blow the trumpet, or all the hundred cows will rush out. "

Knowing that this is an immortal, they went home happily and planned how to carry the Taurus. The elder sister wanted to take out a hundred heads and give them to the poor villagers. The younger sister wanted to blow the trumpet to give the Taurus to the villagers. Finally, the younger sister's idea was approved.

Sure enough, the mountain eye became bigger at night, but only one person was allowed to go in. My sister went in, and my sister followed her later. Taurus became alive as soon as she blew the trumpet, but when the last one came out, the sun rose slowly, and the mountain eye became smaller. The two sisters pushed the cow's butt but couldn't push it.

The villagers worked together to pull the last cow, but the cow was hurriedly kicked, leaving the two sisters in the mountain, and the trumpet of the mountain eye became a flower, so this kind of flower was named in memory of the two sisters.
