Xiaocao, your life is small, but you have your place.

--Tagore.

In the deep night sky, when a nameless little star lit up, I quietly came to the world. The birth of a life is through the reincarnation of the world, so the birth of every life is destined to be extraordinary in life. So, by the most beautiful dawn of the morning, I searched for my own constellation.

I remember Gu Cheng once said: "The night gave me a pair of black eyes, I used it to find the light, and the day gave me a pair of white wings, and I used it to explore the depth of the night." Indeed, every life is a forbidden fruit that Adam and Eve stole to eat, and every life is destined for an extraordinary journey.

No matter what, you will always have a place in your life. No matter how big or small the position is, you'll always have a spot. It's just that when we are destined to be ordinary, we learn to struggle, we have to break free from the night, to find the light, to find the most suitable place in life.

Life is only once for everyone, and there is a limited amount of time! After a lifetime, we always have to find our own footprints, our own place. A poet walked by, and the history book recorded the "poet fairy"; A philosopher walked by, and Kant was drawn in people's minds; A leader walks by, and life recites "the leader of the people"...

When they were there, they found their place, and when they left, history filled the blanks with their names. We need to tell the world that we have been here and that we have left. In this finite life, seize the place that nature has given you and let the world remember your name.

The grass is fragile, but it has an inch of soil under its feet; Life is fragile, but we need our place. Everyone, as soon as they are born, stands at the bottom of life, they need to struggle, they need to pay, in order to climb the tall building.

There is no endless road in the world, and there is no mountain that cannot be climbed. The farthest road is our feet, and the highest mountain is our ambition. Positioning the position of our pursuit at an appropriate height, spilling the sweat of struggle and shedding the blood and tears of sacrifice towards it, we have no regrets in such a life.

There are inevitably bumps in life, countless ups and downs, and thorns in order to hone our will, and to cross it, it is a sea and a vast sky. It is true that when you lose your place in society, when you lose your position in your profession, when you lose your place in love, you may be sad and cry. But don't forget that no matter what, you have life and the most exalted position that nature has given you.

If it is a small grass, it must have an inch of fertile soil.

If it's a light, it will illuminate the night.

If you are a star, you must have your own sky.

Grapes are a kind of fruit that we often eat in our daily life. There are different fruit colors such as white, green, red, brown, purple, and black. The fruit ripening period is 8 October, and the grapes have been cultivated in China for more than 2,000 years, and it is said that it was introduced by Zhang Qian, a person in the Han Dynasty.

There are many varieties of grapes, about 60 kinds in the world, including about 25 in China.

Grapes have a high nutritional value. The sugar in grapes is mainly glucose, which can be quickly absorbed by the body. When the human body has hypoglycemia, if you drink grape juice in time, the symptoms can be quickly relieved; French scientists have found that grapes can prevent thrombosis better than aspirin, and can reduce the level of serum cholesterol in the human body, reduce the cohesion of platelets, and have a certain effect on the prevention of cardiovascular and cerebrovascular diseases; The flavonoids contained in grapes are powerful antioxidants that fight aging and scavenge free radicals in the body. Grapes contain an anti-cancer trace element (resveratrol) that prevents healthy cells from becoming cancerous and stops cancer cells from spreading.

Grape juice can help patients with organ transplant surgery to reduce rejection and promote early childhood**.

Grapes are not only delicious but also highly nutritious. Ripe berries contain 15%-25% glucose and many minerals and vitamins that are beneficial to the human body.

Grape is a tonic medicine that has the effect of tonifying deficiency and strengthening the stomach. People who are weak and malnourished, eat more grapes or raisins to help restore health, because grapes contain protein, amino acids, lecithin, vitamins and minerals and other nutrients, especially the high content of sugar, and mainly glucose, which is easily absorbed by the human body directly.

Although grapes are delicious, diabetics and constipation should not eat more; People with spleen and stomach deficiency should not eat more, and eating too much will make people diarrhea.
