The construction of "Education Cloud" platform is an important task in the "Thirteenth Five-Year Plan" of national education informatization. It is the basis for providing information-based teaching services and high-quality educational resources for schools, teachers, students and parents, and it is also an important guarantee for promoting the balanced development of education. In recent years, China Telecom has continuously increased its investment in education informatization, accelerated the coverage of optical fiber network, built a service platform, and innovated application cooperation, and fully supported the construction of "three links and two platforms" in education departments at all levels with the smart campus solution of "safety, intelligence and coordination", and achieved remarkable results. In 20 15, China Telecom has built 102 educational cloud platforms, and in 20 16, 200 more will be built. In March this year, the Ministry of Education signed the second strategic cooperation agreement with China Telecom. The two sides plan to further deepen cooperation in eight aspects, such as "three links and two platforms", from 20 16 to 2020, to promote the deep integration and innovative development of education, teaching and information technology, accelerate the process of educational modernization and accelerate "Internet+education". The delegates also visited the Ningbo Telecom Education Cloud Room and the Ningbo Smart City Pavilion, and saw the achievements and successful cases of educational informationization such as "Shang Yong Cloud School", cloud recording and broadcasting, ubiquitous teaching terminal (e-book bag), supporting teachers' remote evaluation of classes, and three courses of education, which were highly appreciated by the delegates.
