What software equipment does the teacher use to teach now?

Computer, USB flash drive, bee. Basically, every teacher will bring it, especially female teachers. Their voices may not be as loud as those of male teachers, so they need to bring a little bee. Generally, teachers with USB flash drives will use WPS software, or some videos of Tencent Youku, and will play PPT, so that you can see the teaching content more intuitively. As for those videos, I will give you some extra-curricular knowledge.
