The Second Experimental Primary School of Hongjiang District, Baishan City, Jilin Province was established in 1959 and has a long history of education. In 1989, it was named as the Experimental Primary School of Tonghua Mining Bureau by the Education Commission of Jilin Province. In 2006, it was transferred from the enterprise to local management and renamed as the Second Experimental Primary School of Hongjiang District. In order to earnestly implement the Party's educational policy, comprehensively promote quality-oriented education, and effectively improve the quality of education and teaching, the school has proposed the educational philosophy of "Respecting life, accompanying books, and growing independently". The Experimental Primary School of Hongjiang District can choose Chenlian video conferencing system to achieve home-school interaction, online office, intelligent test paper generation, online lesson preparation, score inquiry, resource download, student registration management, forum communication, class management, and educational administration through this system. 

At all levels, the education authorities and schools can hold various working meetings and conduct various forms of training and teaching through video conferencing systems. Remote teaching can also save a lot of resources and costs, because one teacher can teach thousands of students simultaneously, and a good course can be used in different regions for several weeks or months. 

Due to the limited number of experts and senior teachers, this teaching technology enables them to play a greater role and solves the problem of whether the school branch students can receive lessons from the best teachers. Distance teaching can enable teaching to span a wide geographical area, which will have great value for education in remote areas of our country. 

The video conferencing system not only offers smooth voice communication and clear video images, but also provides data processing functions such as document sharing, WEB sharing, collaborative browsing, electronic whiteboard, desktop sharing and remote control collaboration. Through the network, teachers and students from different places can communicate with each other in real time via audio and video, as if they were in the same classroom.
