    The new height of Mount Qomolangma is 8,848.86 meters. The result was announced by China and Nepal together on December 8,2020. The two countries called the mountain "an important symbol of the friendship between Nepal and China".

A team of Chinese surveyors climbed the mountain on May 27,2020. They remained at the peak（峰顶）for nearly two and a half hours. This was a new record for Chinese climbers Some Nepalese surveyors reached the top of the mountain in May. 2019 to carry out measurements（测量）. The two countries reached an agreement on the height of the mountain before the announcement.

In 1975. Chinese surveyors measured Mount Qomolangma as standing 8,848.13 meters above sea level. During that survey, the Chinese team put a survey marker（测标）up on top of the peak for the first time. Another Chinese survey suggested that the mountain's height may have changed after a 7.8-magnitude（震级）earthquake hit Nepal in 2015. comparing with that of 8,844.43 meters in 2005.

    Your Internet experience is ruined when the net speed is too slow—it takes so long to open a web page and the show you're watching stops every few minutes. That can be very boring. But it could be a thing of the past. China's major telecom carriers（电信运营商）will start to provide 5G services in China.

The "G" in 5G refers to the generations of mobile technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data（数据）and the Internet, and 4G made all of these things faster.

Now 5G promises much faster speed, and more stable（稳定的）connections. This means that you will be able to download（下载）an entire HD movie in seconds and only experience a short delay（延迟）between sending and receiving data.

According to the Straits Times, 5G will be able to improve many advanced technologies. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid probable dangers. Meanwhile, 5G-enabled wearable products will keep doctors in touch with their patients and warn them immediately if there's something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make games feel even more real.

But 5G is not perfect. For one thing, 5G will not "travel" far. On 4G networks, you can be 10 kilometers away from the nearest transmission base（传输基地）. But 5G will only cover about 300 meters, meaning that we will need more transmission bases so that we can get signals. And in order to use 5G, we have to buy new products specifically designed for 5G that are expensive now.

The Double Ninth Festival is a special day for old people in China. It started long ago.  Activities are held to show love and respect（尊敬）to old people.

Respecting old people is a tradition in China. That's because the Chinese know that older people have knowledge and experience that young people can learn.  When an older person enters a room. everyone stands up. People are introduced from the oldest to the youngest. When we present something to an older person, both hands are used.

In western countries, however, older people seldom think they are old.  They'd rather do everything themselves. Even after retirement（退休）, they take up hobbies, part-time jobs and new activities to keep their bodies working well. But of course among westerners, older people are respected, too. Usually, seniors don't have to buy tickets for trains or buses. They are given discount（折扣）in stores and restaurants.

 For holidays, the families usually meet at their grandparents' home, and a great smile and a warm hug for their parents are enough for grown-up children to show their respect.
