The first generation offers learns teaching materials and related information as well as other associated education website links.
In addition to offering online learning materials, the second generation as well requests learners to conduct two-way asynchronous communications via emails, e-bulletin boards, and online exercises and measures.
The workload of plenty of network course development is just two to three weeks’ work by two to three persons with the contents of nothing but piling up classroom teaching materials

Polyurethane insulation board Good insulation performance Excellent thermal performance and water resistance, is currently the lowest thermal conductivity and the highest thermal resistance insulation materials in building materials, impermeability, and long service life.
Disadvantage is the poor material physical stability, no price advantage.
In the original design, building's exterior surface dilapidated, many decorative material has been peeled off, the outer decoration surface layer multiple hollowing, seriously affect the appearance and use of buildings.
