After fulfilling the e-learning of e-government in Yunnan, the system will give the training for civil servants from 53 departments.
This isn't a real e-learning, though it also lists some course such as spoken-English training, Java script and senior system engineer, etc
Lower quality of the civil servants' training Compared with the west countries, the government training in China remains room to develop.
Thus, it can be plugged into web browsers when civil servants use it as a learning assisted tool.
V.Conclusions E-learning in the civil servants' job-training is attracting interest not simply as a tool for innovating the civil servants' job-training and developing education system, but also for prompting social cohesion , actualizing educational welfare and encouraging international cooperation.

The concept that the civil engineering infrastructure may be streamlined through the use of Smart technology has been mooted for well over a decade.
Within the civil engineering portfolio bridges have consequently seen by far the greatest proliferation of experimentation with sensing systems.
This particular fibre optic sensor is now well established and accepted within broad sectors of the civil engineering community and has evolved from being an instrument under test in its own right to an instrument which can be used to test and monitor civil engineering construction procedures.
