After school today, I went home, put down my schoolbag, and started doing homework. I was doing my Chinese homework seriously, and a fly flew onto my leg. I found that it didn't bite me, and then I looked at it carefully. It was rubbing its hands and I didn't know what it was doing. The fly also had many small eyes. I waved my hand and it flew away as if it had seen it. I really wanted to explore its secrets.

I checked on my mobile phone and found that flies rub their hands because they want to keep their hands and feet clean so as not to affect their flight. The second is to keep the sense of taste sensitive. It has taste receptors on its feet and will constantly dip its feet around. After tasting the taste, it will rub it again. The third is to spread pathogenic bacteria, stick the bacteria to your feet, land on food, and start rubbing your feet to remove the bacteria from your feet.

Flies have two pairs of compound eyes. Each compound eye is composed of more than 400 single eyes, so it can see above, below and behind, and can see objects within almost 360°. The small eye is very delicate in structure. It has a laser device like a convex lens, called an ophthalmoscope. Each small eye has a cornea and a lens, which can produce images independently. How many small eyes there are can form as many pictures at the same time. To be honest, flies can see in all directions and hear in all directions.

Today, our family has cold preserved eggs, and my mother asked me to peel the preserved eggs. I first took a basin of water and put four lovely preserved eggs in it. I used a knife to scrape off the mud on the preserved eggs one by one. After scraping it clean, I poured out the dirty water, then took a basin of clean water and put the preserved eggs in. The dirty preserved eggs became clean.

Take out the preserved eggs, crack the shells, take out the eggs inside and put them into a bowl. Use chopsticks to divide the eggs into four parts, and finally start to cool them.

This is my personal practice of making cold preserved eggs: five preserved eggs, cut into four slices and placed on a plate. There is not a little meat, an appropriate amount of garlic, chili sauce and soy sauce are set aside. After heating the pot, add oil, garlic, meat, soy sauce, chili pepper in order, stir-fry the chili sauce until oil comes out, sprinkle a layer of sugar on the preserved eggs, and mix the ingredients in the pot. Pour the ingredients on the preserved eggs and sprinkle with chopped green onion. Taste: cool and refreshing, delicious taste.

I felt so happy when I tasted the cold preserved eggs I made for the first time. I couldn't be happier to see my family finishing all the preserved eggs! Although I left behind the sweat of labor, I experienced the joy of life.
