What makes this chip special is its ability to cover a very wide frequency range (频率范围)—from 0.5 GHz to 115 GHz. That is, one single chip can replace several separate devices that were needed to handle different frequency bands in the past. Also, the chip's transmission (传输) speed can be over 120 GB per second. That is fast enough to download many high-quality movies in just one second.

What makes this chip even more amazing is its intelligence. It can automatically find out which frequency bands are busy. Then it can switch to the ones that are not being used. This helps keep the connection more stable and reliable, even in difficult environments.

The technology uses a special material called lithium niobate (铌酸锂). This material lets the chip process signals well. At the same time, it reduces power consumption (功耗), which makes it more environmentally friendly. This new idea solves a key problem in making 6G systems work in real life.

This big breakthrough shows that future 6G networks may support new and advanced uses. For example, they can help doctors do operations from far away and help with advanced VR. They can also make perfect connectivity possible. For example, you can stay connected from the deep sea to outer space without stopping. Right now, the research team is trying to make the technology smaller. They want to put it into different devices in the future.

This progress shows that China is getting increasingly stronger in next-generation communication technology. It also brings us one step closer to the 6G era.

Not only did this movie become one of the biggest surprises of the summer, but HUNTR/X's theme song Golden also started a heated discussion when it came out. Earlier this month, with this inspiring song of self-discovery, strength and unity, HUNTR/X climbed the charts from No. 81 to No. 1 on the Billboard Top 100. This marks the first time any K-pop girl group, virtual (虚拟的) or real, has achieved this, according to the Billboard. Besides, Spotify recently announced that the song had already been played over 6 million times.

Unlike other virtual idols, HUNTR/X gained huge popularity for an existing hit movie. It includes familiar roles, like a cool leader, a lovely youngest member and a tough rapper. This makes it easier for fans to connect with the characters.

However, their success raises important questions about the future of the music industry, and the Internet is divided. While some fans were attracted by the group's creativity and cheered for the victory, others have argued that a virtual group shouldn't be counted. Many of them have argued that it is unfair to the people who spend years training so hard with the hopes of becoming a successful artist.

In Asia, virtual artists are common, but HUNTR/X is special as a virtual K-pop group from a movie that has been extremely popular with Western audiences. Undoubtedly, HUNTR/X's success suggests the beginning of a new chapter in pop culture—virtual groups could play an important role in global music. Whether virtual idols will become the new normal remains to be seen, but as reported by billboard, we can already see that HUNTR/X is changing what is possible in music.

The young man then told him the following story.

When I was a little boy, I used to be very quiet. At that time my parents were busy with their work. I had to live with my grandparents. It seemed that nobody cared much about me.

One day, a friend of mine, Martin, came in with a nice new watch. It shone brightly in the sun, so when I saw it fall out of Martin's pocket, I picked it up and put it into my own pocket.

Shortly later, Martin noticed that his watch was missing and immediately told you about it. You told the class that whoever took it or found it and kept it, he should return it. I didn't give it back. You closed the door and told us all to stand up and form a circle. You were going to search our pockets. However, you asked us to close our eyes because you would only look for his watch if we all had our eyes closed.

You searched my pocket and found the watch there. You kept searching everyone's pockets and when you were done, you said, "We have the watch." You never said who took the watch to save my dignity forever. But it was the greatest shame of my life. You never said anything. You never shouted at me or took me aside to give me a lesson. I received your message clearly.

"Do you remember this story, Mr. Wilson?" The old man answered, "Yes. I remember the situation with the missing watch but I didn't remember you because I closed my eyes, too. You know, young man, I gave knowledge and I also did what a teacher would do for students."

A birthday usually comes with a party, as well as a cake, presents and wishes from friends. But beyond these, what does a birthday really1?

One year, I spent my birthday2 in a completely new place. Calls and messages poured in as usual. However, I was3 what to do. I had nowhere to go. I didn't know anyone to share the4 with, either.

At that moment, my mother called me, asking, "What are you5 for your birthday?"

"I'm not sure, Mum. There's no one here. I'm so far from home..." Although my voice was so6, I could still hear it clearly in this empty, quiet room. "You don't always need a lot of people for your birthday. Just follow your heart and make this day yours." What Mum said made me less upset.

Then I picked up a book and lost myself in it, with music on. I did as my mother had told me and7 "my own day". Unexpectedly, I experienced something new—I got connected with my inner self. It was a8 but lovely day. I realized my9 for the first time—from a preschool child who shared birthday chocolate with the class to someone who could now celebrate with myself.

When I lay in bed that night, I remembered my mother's words, "You came into our lives this day. We are thankful for it." And indeed, that is the true meaning of birthday celebrations—the valuable gift of10 itself. From the moment we are born, every day is a new chance to learn, to love, and to enjoy the world around us.

David got a special and pretty gift on his birthday—a hand-made kite with a long tail. The kite was1 beautiful that David wanted to show it to everyone. In the afternoon, he took the kite and followed his grandpa to an open space. He felt happy and sang all the way2.

The wind was strong that day, perfect for3. It was4 for David to let the kite go and watch it dance beautifully in the sky.

Suddenly, the wind changed its direction. David lost control of the kite, and it fell into5 tree. It took them half an hour6 back the kite. However, they found7 tail fell off. David's heart dropped.

8 David came home with it, his grandpa noticed his disappointment and comforted him softly, "Come on. I'll make one9 you."

They went to a nearby shop. David's grandpa borrowed10 tools, cut a paper tail and stuck it to the kite.

"Things break sometimes, just like this beautiful kite," his grandpa said, "but face them calmly11 everything will work out."

Once the kite12, David hurried out and let the wind lift the kite again. It flew even higher! David couldn't wait to share the great news with13.

When the sun began to set, they headed back home. On their way, David said to his grandpa, "I never thought the kite14 be fixed, but it turned out much stronger."

His grandpa15, "Being strong is not about never falling. It is about always rising again."
