For this feedback link, the bird has a very special intelligent application, that is, intelligent training housekeeper. For example, there are more than 1000 people in our headquarters alone, not to mention the branches and agents scattered around. The intelligent training housekeeper can learn all the information such as work industry, live broadcast distribution, subject type, course results and training results through data collection in different dimensions.
I just need to log in to the data background and easily solve a big problem.
