【推荐1】On the evening of April 8, Dunhuang Academy and Huawei jointly launched a brand-new technology-driven tour experience at the Mogao Grottoes. Using Huawei's newly-released Hetu artificial intelligence platform, coupled with the output of the Digital Dunhuang project, visitors to the Mogao Grottoes can enjoy a fantasy experience prior to entering the attraction.

Zhao Shengliang, director of the Dunhuang Academy, said that it has been cooperating with Huawei since March 2019. Using Huawei's latest Hetu technology, visitors are able to see the detailed contents of the Dunhuang Art Murals(壁画) outside the caves, through their Huawei mobile phones. This will reduce the time tourists spend inside the cave, aiding the protection of the cultural relics, while at the same time helping to increase the amount of information visitors can obtain. It is also considered to be a new way of promoting Dunhuang Art.

The Dunhuang Academy has used digital technology to preserve the research and exploration of Dunhuang Grottoes since the early 1990s. It has collected a wealth of data and has realized the goal of sharing of digital Dunhuang globally. It has played an important role in the protection and research of cultural site, as well as promoting the development and progress of related work.

The Huawei Hetu platform unites Dunhuang's study findings, high—resolution images of the site's murals and virtual, three-dimensional models with the real Mogao Grottoes. It has not only re-created the real tour of the scenic spot, but also developed a new way of digitally experiencing the grottoes. When people visit the site, they not only have the experience of seeing the real grottoes, but they can appreciate the admirable artworks more clearly and in greater detail.

In the future, Dunhuang Academy will continue to cooperate with Huawei to create more colorful virtual content to enrich the experience of Mogao Art on the platform, helping people around the world get to know Dunhuang Art better.

In May, the US Department of Education (ED) published its findings that the number of homes without access to the Internet has been getting smaller, but 14 percent of homes in city areas and 18 percent of homes in the countryside still do not have Internet connections.

In some states, the problem is much more serious. For example, in the countryside of northern Mississippi, a third of the 294 homes in Maben do not have computers. And close to half have no access to the Internet whether they can pay for it or not.

Sharon Stidham, a mother in Maben, has to take her four boys to the school library at East Webster High School. Her husband works there, so the children can use the Internet for their schoolwork. A signal tower can be seen through the trees from their home, but they could not put aside any money for the Internet.

Research results from the National Center for Education Statistics (NCES) have shown that students with the Internet at home get much better scores in reading, math and science than the ones without.

Some teachers call this problem “the homework divide”. Jessica Rosenworcel, an NCES member, said, “The so-called homework divide is the cruelest part of the digital age and it is hurting the poor students and creating a big obstacle to their dreams.”

Local communities(社区) have started to help. They made lists of restaurants and other businesses with Wi-Fi places where children are welcome to come and do their homework. And many public libraries have also planned to provide free access for the students next year.
