Problems solved by technology

[0003] At present, when users watch teaching videos played by teachers or have video conversations with teachers online through smart devices, if they cannot understand certain knowledge points mentioned by teachers in teaching videos or in the process of talking with teachers, general users do not interrupt the The teacher's explanation ideas or not disturbing other students to watch the teaching video can only be understood by querying the knowledge points afterwards
[0004] However, most users may have forgotten what knowledge points they did not understand during the teaching process after the end of the video teaching, or there is no time to query the knowledge points because they are busy with other things afterwards, which will lead to knowledge that users do not understand. Points cannot be answered in time, which reduces the quality of video teaching and the learning efficiency of users
