Dear teachers, classmates, and parents,

Good morning! Today, I'm going to talk to you about something that has been a part of our lives for a long time now – the COVID-19 pandemic. It's a big word, but don't worry, I'll make it simple for us to understand.

First of all, let's imagine the world without borders. It's like a big village where everyone is connected and can visit each other anytime they want. But then, something happened that made this village very quiet and everyone stayed home. That something is called a virus, and this particular virus is called COVID-19. It's like a little monster that travels through the air when someone coughs or sneezes, and it can make us sick.

Now, why did we have to stay home so much? Well, just like how we play hide-and-seek, this virus likes to hide in our bodies and make us feel bad. It can make us cough, have a fever, or even feel very tired. And if we don't take care of ourselves, it can be very dangerous. That's why doctors and nurses wore special clothes called "防护服" (protective suits) and masks to keep themselves safe when they took care of people who were sick.

But wait, how did we know about this virus in the first place? That's where scientists come in! They are like super detectives who use their smart brains and special tools to find out what's going on. They found out that this virus was different from others we knew before, so they named it COVID-19 and worked hard to understand how it works.

One important thing scientists discovered is that this virus likes to spread from one person to another when we're not careful. That's why we learned about "social distancing" – keeping some space between us when we're around others. It's like playing tag but without touching each other! We also learned to wash our hands a lot, just like singing "Happy Birthday" twice under running water. And don't forget, covering our mouths when we cough or sneeze with our elbows or tissues.

Now, let's talk about how brave our community became during this time. Just because we couldn't see each other as much doesn't mean we didn't care. We sent letters to our friends, drew pictures, and even had virtual parties on video calls. It was a way of saying, "I miss you but I'm doing my part to stay safe." Our parents and teachers worked hard to make sure we could still learn and play safely at home. And the grown-ups outside our homes – like doctors, nurses, and delivery people – were heroes for keeping us going with their bravery and hard work.

One thing I learned from this experience is that even though we might feel scared or lonely sometimes, we can always find ways to be kind and help each other. Just like how my mom taught me to share my toys with my little brother even though I wanted to keep them for myself. It's the little acts of kindness that make a big difference.

And speaking of heroes, let me tell you about my own little hero – my dad! He's a doctor, and he went to work every day during the pandemic. He wore that special suit and mask to help sick people get better. I missed him a lot when he was gone, but I knew he was doing important work. When he came home, I gave him a big hug and thanked him for being brave. That's what heroes do – they protect us without thinking twice.

In the end, even though COVID-19 might still be around for a while, we know how to fight it now. We wear masks, wash our hands, and stay away from each other when we need to. And just like how spring always comes after winter, there will be better days ahead when we can hug each other again without worrying.

So, my dear friends, let's keep being smart and kind. Let's keep learning and growing, just like how plants grow through the rain and sun. And remember, every little action we take helps in making our world a safer place. You are all little heroes too, for being patient and brave during these times.

Thank you for listening!
